Description

Technical Field

[0001] This application relates to the technical field of rare gas purification, and in particular to a Kr chromatography separation method, system, terminal and storage medium based on multi-channel switching. Background Technology

[0002] A chromatographic column is a cylindrical container used for chromatographic separation and analysis, which can separate the components in a sample gas through a stationary phase inside the column.

[0003] In related technologies, multi-channel switching chromatographic column separation technology refers to selecting different channels for sample gas based on its type. The chromatographic column in the corresponding channel specifically adsorbs impurities in the sample gas. Then, by switching valve passages, a secondary separation operation is performed on the sample gas, thereby further improving the purity of the target separated gas.

[0004] Regarding the aforementioned technologies, when separating sample gases using multi-channel switching chromatographic column separation technology, the different types of components and their concentrations in the sample gases being separated mean that a fixed column switching scheme cannot dynamically adjust the column combination and switching timing based on data differences such as sample gas component types. This results in low column separation efficiency and room for improvement. Summary of the Invention

[0005] To improve separation efficiency, this application provides a Kr chromatography separation method, system, terminal, and storage medium based on multi-channel switching.

[0006] Firstly, this application provides a Kr chromatographic separation method based on multi-channel switching, employing the following technical solution:

[0007] A Kr chromatographic separation method based on multi-channel switching, comprising:

[0008] The preset sample gas is passed into a preset quantitative tube for storage, and the sample gas components and sample gas component concentrations are collected.

[0009] The sample gas components and their concentrations were analyzed to determine the target column connection topology and separation scheme.

[0010] Collect actual column connection topology diagrams;

[0011] Determine if the actual column connection topology matches the target column connection topology. Figure 1 To;

[0012] If they match, the metering tube will be used to pass the stored sample gas into the column corresponding to the actual chromatographic column connection topology for separation.

[0013] If there is a discrepancy, the working status of the preset column valves will be adjusted according to the target column separation scheme, and the quantitative tube will be controlled to introduce sample gas into the target column connection topology for separation operation.

[0014] Optionally, the steps of analyzing the sample gas components and their concentrations to determine the target column connection topology and separation scheme include:

[0015] Collect sample air type and chromatographic column separation protocol library;

[0016] The sample gas type is determined from the sample air types based on the sample gas composition and sample gas composition concentration.

[0017] Based on the sample gas type, the target chromatographic column separation scheme is found in the column separation scheme library, and the target chromatographic column connection topology is found in the target chromatographic column separation scheme.

[0018] Optional steps for acquiring sample air type and chromatographic column separation protocol library include:

[0033] The actual column number is compared with the separation column number to generate the discontinued column number;

[0034] Determine whether the column number to be shut down meets the preset column shutdown requirements;

[0035] If the condition is met, the valve of the corresponding chromatographic column will be closed according to the serial number of the stopped chromatographic column, and the actual chromatographic column serial number will continue to be collected for cyclic judgment.

[0036] If the conditions are not met, the corresponding column valves will be controlled according to the column separation sequence, column number, and target column separation time.

[0037] Optionally, the steps for acquiring the separation time of the target chromatographic column include:

[0038] The initial column separation time is found in the preset column separation time sequence correspondence based on the column number.

[0039] Historical column separation times were collected and summarized to generate a historical separation time database;

[0040] The actual separation time of the chromatographic column is found in the historical separation time database based on the separation column number.

[0041] The initial column separation time is compared with the actual column separation time to generate inconsistent separation times;

[0042] Determine whether the inconsistency separation time meets the preset correction separation time requirement;

[0043] If the conditions are not met, the initial column separation time will be determined as the target column separation time.

[0044] If the conditions are met, the actual column separation time is corrected based on the inconsistent separation time to generate the target column separation time.

[0045] Optionally, the step of correcting the actual column separation time based on inconsistent separation times to generate the target column separation time includes:

[0046] Collect the historical operating status of the column valves corresponding to inconsistent separation times;

[0047] Determine if the historical working status is a preset abnormal valve working status or a preset abnormal parameter working status.

[0048] If the valve is in an abnormal working state, the initial column separation time will be determined as the target column separation time.

[0049] If the parameter is in an abnormal working state, the inconsistent separation time is determined as the separation time that needs to be corrected based on the historical working state.

[0050] The initial column separation time was compared with the actual column separation time to generate a consistent separation time;

[0051] The required separation times and consistent separation times are summarized to generate the target column separation time.

[0052] Secondly, this application provides a Kr chromatography separation system based on multi-channel switching, employing the following technical solution:

[0061] In summary, this application includes at least one of the following beneficial technical effects:

[0062] 1. By analyzing the sample gas components and their concentrations, the connection topology and separation scheme of the target column are determined, and it is determined whether the actual column connection topology matches that of the target column. Figure 1 If they match, the metering tube is controlled to pass the stored sample gas into the column corresponding to the actual column connection topology diagram for separation. If they do not match, the working state of the column valve is adjusted according to the target column separation scheme, thereby controlling the metering tube to pass the sample gas into the target column connection topology diagram for separation, so that the sample gas is separated under the optimal column separation scheme to improve the separation efficiency of the column for the sample gas.

[0063] 2. By identifying the sample gas type from the sample air type based on the sample gas composition and concentration, and then finding the target chromatographic column separation scheme from the column separation scheme library based on the sample gas type, and finally finding the target chromatographic column connection topology from the target chromatographic column separation scheme, we can provide data support for adjusting the chromatographic column combination based on the target chromatographic column separation scheme and the target chromatographic column connection topology, thereby improving the separation efficiency of the chromatographic column.

[0064] 3. By finding the separation column number and separation column sequence in the target chromatographic column separation scheme, the separation column numbers are sorted according to the separation column sequence to generate the first separation column number. Then, the working state of the chromatographic column valve is controlled according to the actual chromatographic column number and the separation column number. Finally, the sample gas is input to the corresponding chromatographic column for separation operation by controlling the quantitative tube according to the first separation column number.

[0072] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figures 1 to 7 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0073] This application discloses a Kr chromatographic separation method based on multi-channel switching. This method primarily addresses the multi-channel switching problem and specifically discloses a sample gas, a chromatographic column, a column status monitoring device, a column valve, and a processing terminal. The processing terminal is communicatively connected to both the column status monitoring device and the column valve to achieve data interaction and control. After the column status monitoring device sends the actual column connection topology and the component types and concentrations in the sample gas to the processing terminal, the processing terminal determines the target column connection topology based on the component types and concentrations. It then compares the actual column connection topology with the target column connection topology. When the actual and target column connection topologies are inconsistent, the processing terminal adjusts the opening and closing state of the column valve based on both the target and actual column connection topologies. This aims to quickly and rationally control the opening and closing state of the column valve, thereby determining the appropriate chromatographic column for separation based on the components in the sample gas, and ultimately improving the column separation efficiency.

[0074] Reference Figure 1 This application discloses a Kr chromatographic separation method based on multi-channel switching, comprising the following steps:

[0075] Step S100: Pass the preset sample gas into the preset quantitative tube for storage, and collect the sample gas components and sample gas component concentrations.

[0076] Among them, sample gas refers to krypton-containing gas that needs to be separated by a chromatographic column after pre-purification; quantitative tube refers to a tubular device with a fixed volume used to collect, store and quantitatively deliver gas.

[0077] Sample gas composition refers to the types of molecules contained in the sample gas, and sample gas composition concentration refers to the content of each type of molecule in the sample gas. In one embodiment, the sample gas is sent to a Fourier transform infrared detection device for qualitative and quantitative detection. The qualitative detection result is the sample gas composition, and the quantitative detection result is the sample gas composition concentration.

[0078] Step S101: Analyze the sample gas components and their concentrations to determine the target column connection topology and separation scheme.

[0079] The target column connection topology diagram refers to an image that uses symbols to reflect the connectivity and sequence between the columns and valves corresponding to the target column separation scheme. The target column separation scheme refers to a data set storing the column number, separation sequence, and required time for each column to maximize the separation efficiency of the sample gas. Specific methods are described in [reference needed]. Figure 2 This process provides data support for subsequent adjustments to the column connections based on the target column connection topology and separation scheme.

[0080] A chromatographic column is a cylindrical container used for chromatographic separation and analysis. It can separate the components in a sample gas through the stationary phase inside the column. It consists of three chromatographic columns with different separation functions and corresponding column valves.

[0081] A column valve is a module connected to the inlet and outlet of each column to control the flow of gas.

[0082] Step S102: Collect the actual column connection topology diagram.

[0083] The actual column connection topology refers to the image that shows the connection relationship and sequence between the corresponding columns and valves through symbols during the last separation operation. The actual column connection topology can be obtained by querying the historical data based on the separation time closest to the current separation time through the processing terminal.

[0084] Historical data refers to a collection of data used to store chromatographic column separation schemes and column connection topology diagrams for all separation operations. Historical data can be obtained by classifying and storing relevant data from each separation operation according to the end time of the separation operation through a processing terminal.

[0085] Step S103: Determine whether the actual column connection topology matches the target column connection topology. Figure 1 To.

[0086] Specifically, after the processing terminal determines the actual column connection topology and the target column connection topology, the processing terminal judges whether the actual column connection topology matches the target column connection topology. Figure 1 This allows us to determine whether the operating status of the column valves needs to be adjusted.

[0087] Step S1031: If consistent, control the quantitative tube to pass the stored sample gas into the chromatographic column corresponding to the actual chromatographic column connection topology diagram for separation operation.

[0088] In this case, if the processing terminal determines the connection topology of the actual chromatographic column and the connection topology of the target chromatographic column... Figure 1 If the result is correct, it means that there is no need to adjust the working status of the column valve. Therefore, the processing terminal searches for the column separation scheme corresponding to the actual column connection topology in the historical data, and controls the quantitative tube to pass the stored sample gas into the corresponding column for separation operation according to the column separation scheme.

[0089] Step S1032: If there is no consistency, adjust the working status of the preset column valve according to the target column separation scheme, and control the quantitative tube to introduce sample gas into the target column connection topology diagram for separation operation.

[0090] If the processing terminal determines that the actual column connection topology is inconsistent with the target column connection topology, it indicates that the working status of the column valves needs to be adjusted. Therefore, the processing terminal controls the column valves to adjust their working status according to the target column separation scheme. The specific method is described in [reference needed]. Figure 4 The steps involve controlling the flow of sample gas through the quantitative tube into the target chromatographic column connection topology for separation.

[0091] The column valve in this step is the same as the column valve in step S101 above, and will not be described again here.

[0092] Reference Figure 2 The steps for analyzing the sample gas components and their concentrations to determine the target column connection topology and separation scheme include:

[0093] Step S200: Collect sample air type and chromatographic column separation protocol library.

[0094] Here, "sample air type" refers to the set of all possible combinations of gaseous components in the sample air at different concentrations; "chromatographic column separation scheme library" refers to the data set used to store the column number, separation order, and required time for each combination of sample air types, which corresponds to the highest separation efficiency. For specific methods, refer to [reference needed]. Figure 3 This process provides data support for subsequently determining the target column separation scheme and the target column connection topology.

[0095] Step S201: Determine the sample gas type from the sample air types based on the sample gas composition and sample gas composition concentration.

[0096] In this process, after the processing terminal determines the sample gas components and concentrations, it performs a matching search in the sample air type based on the sample gas components and concentrations, and determines the combination of data that matches the sample gas components and concentrations as the sample gas type.

[0097] Step S202: Based on the sample gas type, find the target chromatographic column separation scheme in the column separation scheme library, and find the target chromatographic column connection topology in the target chromatographic column separation scheme.

[0098] In this process, after the processing terminal determines the sample gas type, it searches the column separation scheme library for matching based on the sample gas type and identifies the column separation scheme that matches the sample gas type as the target column separation scheme. After the processing terminal determines the target column separation scheme, it queries the target column separation scheme to obtain the target column connection topology diagram.

[0099] Reference Figure 3 The steps for collecting sample air type and chromatographic column separation protocol library include:

[0100] Step S300: Enumerate the preset sample air components and preset component concentration types to generate sample air types.

[0101] In this step, the sample air type is the same as that in step S200 above. The sample air composition is first fixed into easily separable gas components by the processing terminal, and then the high, medium and low concentrations of the component concentration types are iterated. Then the sample air composition is fixed into difficult-to-separate gas components, and the high, medium and low concentrations of the component concentration types are iterated. The combination generated by the two fixing methods is summarized to obtain the sample air type.

[0102] The sample air composition refers to the set of types of gas components that may exist in the sample air, classified according to the degree of difficulty of separation. In one embodiment, the operator divides and summarizes the gas components that may exist in the sample air according to the degree of difficulty of separation to obtain the sample air composition.

[0103] The component concentration type refers to the set of concentration ranges of three types of gases: high, medium, and low. In one embodiment, the high concentration range is greater than or equal to 100 ppm, the medium concentration range is 1-100 ppm, and the low concentration range is 0.01-1 ppm.

[0104] Step S301: Enumerate the component separation effects of the chromatographic columns corresponding to the preset column numbers to generate combined column separation effects.

[0105] The combined column separation effect refers to the data set of separation effects achieved by combining chromatographic columns in different ways. The processing terminal fixes the separation effect of the component with column number 1 and iterates through the separation effects of the remaining two columns. Then, it fixes the separation effect of the component with column number 2 and iterates through the separation effects of the remaining two columns. Finally, it fixes the separation effect of the component with column number 3 and iterates through the separation effects of the remaining two columns. The separation effects of the three individual columns are then summarized with the above-generated combinations to obtain the combined column separation effect.

[0106] The column number is a numerical mark used to distinguish three chromatographic columns. In one embodiment, the operator can obtain the column number by matching the three chromatographic columns with three different numbers according to the actual situation.

[0107] The component separation effect refers to the set of gas components that the three chromatographic columns can adsorb. In one embodiment, the operator finds the corresponding adsorbable gas components in the chromatographic column technical manual according to the chromatographic column model, and obtains the component separation effect by matching the chromatographic column model with the adsorbable gas components one by one through the processing terminal.

[0108] Step S302: Match the separation effect of the combined chromatographic columns with the sample air type to generate a chromatographic column combination scheme.

[0109] Among them, the column combination scheme refers to the set of column combination schemes that can be separated in the most efficient way in order to achieve the separation of all combinations of sample air types. The column combination scheme can be obtained by matching the separation effect of the combined column with the sample air type through the processing terminal.

[0110] Step S303: Match the column combination scheme with the preset column positions to generate the column valve operation scheme.

[0111] The column valve working scheme refers to the position of the column valve corresponding to each scheme in the column combination scheme. The column valve working scheme can be obtained by the processing terminal according to the one-to-one correspondence between the column combination scheme and the column position.

[0112] The position of a chromatographic column refers to the set of position coordinates of each chromatographic column. By mapping the two-dimensional coordinate system to the entire separation area of ​​the chromatographic column through the processing terminal, the position of a single chromatographic column can be obtained. The position of the chromatographic column can be obtained by summing up the position coordinates of each chromatographic column.

[0113] Step S304: Control the preset column valves to form corresponding pathways according to the column valve working scheme to generate a column connection topology library.

[0114] Among them, the column connection topology diagram refers to the image that reflects the connection relationship and connection sequence between the columns and valves corresponding to the column valve working scheme and column combination scheme through symbols. The processing terminal controls the column valve to form the corresponding path according to the column valve working scheme, and the formed corresponding path is photographed by a camera and uploaded to the processing terminal. The acquired image data is then summarized to obtain the column connection topology diagram library.

[0115] The column valve in this step is the same as the column valve in step S101 above, and will not be described again here.

[0116] Step S305: Match the column connection topology diagram with the column combination scheme to generate a column separation scheme library.

[0117] In this step, the column separation scheme library is the same as that in step S200 above. By processing the column connection topology diagram and the column combination scheme one by one through the processing terminal, the column separation scheme library can be obtained, thereby providing data support for the subsequent determination of the target column connection topology diagram and the target column separation scheme.

[0118] Reference Figure 4 The steps for separation operation, including adjusting the working status of preset column valves according to the target column separation scheme and controlling the quantitative tube to introduce sample gas into the target column connection topology diagram for separation, include:

[0119] Step S400: Collect the actual chromatographic column number.

[0120] The actual column number refers to the set of column numbers used in the previous gas separation operation. The actual column number can be obtained by searching the historical data based on the actual column connection topology diagram in the processing terminal.

[0121] Step S401: Locate the column number and column sequence in the target column separation protocol.

[0122] Among them, the separation column number refers to the set of serial numbers corresponding to the chromatographic columns used to complete the separation operation of the sample gas; the separation column sequence refers to the order in which the sample gas is introduced into the chromatographic columns used to complete the separation operation of the sample gas. The separation column number and separation column sequence can be obtained by searching in the target chromatographic column separation scheme through the processing terminal.

[0123] Step S402: Sort the separation column numbers according to the separation column sequence to generate the first separation column number.

[0124] The first separation column number refers to the number of the first chromatographic column into which the sample gas is introduced. The processing terminal maps the separation column sequence and the separation column number one by one, and determines the first separation column number in the separation column sequence as the first separation column number.

[0125] Step S403: Adjust the working status of the column valve according to the actual column number and the separation column number.

[0126] After the processing terminal determines the actual column number and the separation column number, it controls the column valves to adjust their working status based on these information. The specific method is described in [reference needed]. Figure 5 This process provides support for the subsequent efficient separation of sample gases.

[0127] Step S404: Control the quantitative tube to input the sample gas into the corresponding chromatographic column for separation operation according to the serial number of the first separation chromatographic column.

[0128] In this process, after the processing terminal determines the serial number of the first separation chromatographic column, it controls the corresponding column valve to open according to the serial number of the first separation chromatographic column, and controls the quantitative tube to input the sample gas into the corresponding chromatographic column for separation operation.

[0129] Reference Figure 5 The steps for adjusting the working status of the column valves based on the actual column number and the separation column number include:

[0130] Step S500: Collect the separation time of the target chromatographic column.

[0131] The target column separation time refers to the set of separation times required for each column to separate the sample gas. For specific methods, refer to [reference needed]. Figure 6 This process provides data support for subsequently controlling the operating status of the corresponding chromatographic column valves via a processing terminal.

[0132] Step S501: Compare the actual column number with the separation column number to generate the discontinued column number.

[0133] Among them, the shutdown column number refers to the set of serial numbers corresponding to the chromatographic columns that are not needed when separating the sample gas. The processing terminal compares the actual chromatographic column number with the separation chromatographic column number, and identifies the serial numbers that exist in the actual chromatographic column number but do not exist in the separation chromatographic column number as the shutdown column number, thereby providing data support for subsequent adjustment of the working status of the chromatographic column valve.

[0134] Step S502: Determine whether the shutdown column number meets the preset shutdown requirements.

[0135] The requirement for column shutdown refers to the cessation of operation of all chromatographic columns except those required for the current separation operation, and at least one column number must be among the shut-down column numbers.

[0136] After the processing terminal determines the serial number of the chromatographic column to be shut down, it determines whether the serial number of the chromatographic column meets the requirements for shutting down the column, thereby determining whether there are any chromatographic columns for which the valve needs to be closed.

[0137] Step S5021: If satisfied, control the corresponding column valve to close according to the shutdown column number, and continue to collect the actual column number for cyclic judgment.

[0138] If the processing terminal determines that the serial number of the chromatographic column to be shut down meets the requirements for column shutdown, it indicates that there is a chromatographic column whose valve needs to be closed. Therefore, the processing terminal sends a closing signal to the corresponding chromatographic column valve according to the serial number of the shut-down chromatographic column, and continues to collect the actual chromatographic column serial number through the processing terminal, so as to continue to control the chromatographic column valve to adjust its working status according to the actual chromatographic column serial number and the separation chromatographic column serial number.

[0139] Step S5022: If not satisfied, control the corresponding column valve according to the column separation sequence, column number and target column separation time.

[0140] If the processing terminal determines that the column number does not meet the column shutdown requirements, it means that there is no column whose valve needs to be closed. Therefore, the processing terminal controls the corresponding column valve to work according to the column separation sequence, the separated column number and the target column separation time, thereby providing support for the subsequent control of the quantitative tube to pass the sample gas into the corresponding column for separation operation.

[0141] Reference Figure 6 The steps for collecting the separation time of the target chromatographic column include:

[0142] Step S600: Find the initial column separation time in the preset column separation time sequence correspondence according to the column number.

[0143] The initial column separation time refers to the set of rated times required for each column to separate the sample gas. This time is obtained by the processing terminal by looking up the column number in a mapping table corresponding to the column separation time number.

[0144] The column separation time sequence correspondence refers to the correspondence between the column separation time and the column number. The operator can find the rated separation time of each column for the sample gas in the quantitative tube in the column technical manual according to the column model and the volume of the quantitative tube. The found data is summarized through the processing terminal to obtain the rated separation time of all columns. By mapping the column separation time to the column number to form a mapping table, the column separation time sequence correspondence can be obtained.

[0145] Step S601: Collect and summarize historical column separation times to generate a historical separation time database.

[0146] Among them, the historical column separation time refers to the set of time required for each column to separate the sample gas during the separation operation, which is obtained by searching the historical data through the processing terminal.

[0147] The historical separation time database refers to a collection of data obtained by summarizing the separation times of all historical chromatographic columns according to the date of the separation operation. The historical separation time database can be obtained by summarizing the separation times of all historical chromatographic columns through a processing terminal.

[0148] Step S602: Find the actual separation time of the chromatographic column in the historical separation time database according to the separation column number.

[0149] The actual column separation time refers to the set of the most recent column separation times with the same column number. The processing terminal searches for all column separation times with the same number in the historical separation time database based on the column number, sorts them according to the date of the separation operation, and determines the time data with the most recent date as the actual column separation time corresponding to each column number. Finally, the actual column separation time is obtained by summing up all the sorted time data.

[0150] Step S603: Compare the initial column separation time with the actual column separation time to generate inconsistent separation times.

[0151] The inconsistent separation time refers to the set of actual column separation times that are inconsistent with the initial column separation time. The inconsistent separation time is obtained by comparing each time in the initial column separation time with the corresponding time in the actual column separation time through the processing terminal, and extracting and summarizing the different times.

[0152] Step S604: Determine whether the inconsistency separation time meets the preset correction separation time requirement.

[0153] The corrected separation time requirement refers to the existence of at least one time data point in the inconsistent separation time.

[0154] After the processing terminal determines the inconsistent separation time, it judges whether the inconsistent separation time meets the correction separation time requirement, thereby determining whether the initial column separation time needs to be corrected.

[0155] Step S6041: If not satisfied, the initial column separation time is determined as the target column separation time.

[0156] If the processing terminal determines that the inconsistent separation time does not meet the correction separation time requirement, it means that the initial chromatographic column separation time does not need to be corrected. Therefore, the processing terminal determines the initial chromatographic column separation time as the target chromatographic column separation time, thereby providing data support for the subsequent control of the working status of the corresponding chromatographic column valve.

[0157] Step S6042: If satisfied, the actual column separation time is corrected based on the inconsistent separation time to generate the target column separation time.

[0158] If the processing terminal determines that the inconsistent separation time meets the correction requirement, it indicates that the initial column separation time needs to be corrected. Therefore, the processing terminal corrects the actual column separation time based on the inconsistent separation time to generate the target column separation time. The specific method is described in [reference needed]. Figure 7 This process provides data support for subsequently controlling the operating status of the corresponding chromatographic column valves.

[0159] Reference Figure 7 The steps for correcting the actual column separation time based on inconsistent separation times to generate the target column separation time include:

[0160] Step S700: Collect the historical operating status of the column valves corresponding to inconsistent separation times.

[0161] The historical operating status refers to the set of historical operating statuses of the column valve corresponding to the inconsistent separation time in the most recent separation operation. The processing terminal determines the corresponding column based on the inconsistent separation time, finds the single historical operating status corresponding to each column valve in the historical data, and summarizes the single historical operating statuses to obtain the historical operating status.

[0162] Step S701: Determine whether the historical working state is a preset abnormal valve working state or a preset abnormal parameter working state.

[0163] Among them, abnormal valve working state refers to the situation where the working time of the chromatographic column valve is prolonged or shortened due to control problems such as delay in the response signal of the chromatographic column valve, resulting in abnormal valve working state; abnormal parameter working state refers to the situation where the separation time of the chromatographic column is prolonged due to excessive gas or aging of the chromatographic column during the gas separation process, resulting in abnormal valve working state.

[0164] By processing the terminal to determine whether the historical working status is abnormal valve working status or abnormal parameter working status, it can be determined whether the initial column separation time needs to be corrected.

[0165] Step S7011: If the valve is in an abnormal working state, the initial column separation time is determined as the target column separation time.

[0166] If the processing terminal determines that the historical working status is an abnormal valve working status, it means that there is no need to correct the initial column separation time. Therefore, the processing terminal determines the initial column separation time as the target column separation time, thereby providing data support for subsequent adjustment of the working status of the column valve.

[0167] Step S7012: If the parameter is in an abnormal working state, the inconsistent separation time is determined as the separation time that needs to be corrected based on the historical working state.

[0168] If the processing terminal determines that the historical working status is an abnormal working status, it means that the initial column separation time needs to be corrected. Therefore, the processing terminal determines the inconsistent separation time as the separation time that needs to be corrected based on the historical working status, thus providing data support for subsequent correction of the separation time.

[0169] The separation time that needs to be corrected refers to the set of separation times of chromatographic columns that are in abnormal working conditions in the historical working state. By processing the terminal, the inconsistent separation times corresponding to the chromatographic columns that are in abnormal working conditions in the historical working state are extracted, and the extracted time data is determined as the separation time that needs to be corrected.

[0170] Step S70121: Compare the initial column separation time with the actual column separation time to generate a consistent separation time.

[0171] The consistent separation time refers to the set of time data that are consistent with the time data in the initial column separation time and the actual column separation time. The consistent separation time is obtained by comparing the initial column separation time with the actual column separation time through the processing terminal, and extracting and summarizing the equal time data.

[0172] Step S70122: Summarize the separation times that need to be corrected and the consistent separation times to generate the target column separation time.

[0173] In this step, the separation time of the target chromatographic column is the same as that in the steps above. The separation time of the target chromatographic column can be obtained by summing the separation time that needs to be corrected and the consistent separation time through the processing terminal.
