[0002] In the field of chromatographic detection, due to its convenient and efficient characteristics, automatic samplers have gradually been promoted and applied. In order to meet the detection requirements under different conditions, there are various sample cartridges that can be replaced and selected on one sampler. Because there are various types of sample cartridges that can be replaced and selected, the identification of sample cartridges has become a technical problem to be solved. Summary of the Utility Model
[0003] The purpose of this application is to provide a sample cartridge structure and an automatic sampler that can realize the replacement and identification of multiple different sample cartridges.
[0004] In a first aspect, an embodiment of this application provides a sample cartridge structure, including: a sample cartridge assembly, including a sample cartridge body and an identification member. The sample cartridge body is configured with at least one specification of sample holes, and the sample holes are distributed along a first direction and a second direction, where the first direction is perpendicular to the second direction. The identification member is connected to one side of the sample cartridge body and is located outside the sample cartridge body, and the identification member is configured with an identification portion along the first direction and / or the second direction; a detection assembly, which is configured with a detection portion, and the detection portion is configured to identify the identification portion.
[0005] In the above implementation process, an identification member extends out of the outside of the sample cartridge body, and the detection assembly is placed at the position of the identification member to identify the identification portion of the identification member. The type of the sample cartridge assembly can be distinguished by the position and / or quantity of the identification portion, thereby solving the problem of identifying the sample cartridge assembly, and the identification effect is remarkable.
[0006] In some embodiments, when the sample cartridge body is for double samples, one identification member is configured, and the identification member is configured with one identification portion. The specification of the sample cartridge body for double samples can be identified through this identification portion, and the identification effect is remarkable, improving the efficiency.
[0007] In some embodiments, when the sample cartridge body is for single sample, two identification members are configured, and the two identification members are spaced apart and distributed on one side of the sample cartridge body, and at least one of the two identification members is configured with the identification portion. The specification of the sample cartridge body for double samples can be identified through the combination method of the two identification members, and the identification effect is remarkable, improving the efficiency.
[0008] In some embodiments, the detection component includes a first detection module, and the first detection module is configured with a first detection cavity along the first direction, and the first detection cavity is configured to accommodate the identification member.
[0009] In the above implementation process, when the identification member is placed in the first detection cavity of the first detection module, by setting the identification part of the identification member at different positions, the signals at different positions of the first detection module can be blocked, so as to realize the identification of the sample box body specifications of the single sample box or the double sample box. The identification process is simple, the effect is remarkable, and the efficiency is improved.
[0010] In some embodiments, when the sample box body is a single sample, the detection component further includes a second detection module. The first detection module and the second detection module are spaced apart and distributed on the sample box body, and both the first detection module and the second detection module accommodate the identification member.
[0011] In the above implementation process, the sample box body is a single sample, and there are two identification members arranged at intervals. One identification member is detected by the first detection module, and the other identification member is detected by the second detection module. It can detect the identification parts at different positions of the identification member under the combination of the first detection module and the second detection module, so as to realize the identification of the single sample box. The identification process is simple, the effect is remarkable, and the efficiency is improved.
[0012] In some embodiments, the sample box body is further configured with an identification portion.
[0013] In the above implementation process, through this identification portion, when the user gets the sample box body, the user can quickly identify the sample box capacity size of the sample box body and the number of sample bottles that can be placed, saving the user's identification time, with remarkable effect. At the same time, setting this identification portion on the sample box body will not affect the original structure of the sample box body.
[0014] In some embodiments, the sample box body is further configured with a coordinate system.
[0015] In the above implementation process, by establishing a coordinate system on the sample box body, it can be used to solve the problem that the hole positions are easily ambiguous in description during use due to the lack of identification of the sample box, which is beneficial to the description of the positions where the sample bottles are placed on the sample box body and can avoid description and understanding errors.
[0016] In some embodiments, the sample box body is configured with a first region and a second region. The first region and the second region are located on the same side of the sample box body, and the first region and the second region are configured to set different specifications of the sample holes.
[0017] In the above implementation process, by setting sample holes with different specifications in the first area and the second area of the sample box body, it can be used to place sample bottles with different specifications, effectively solving the problem of insufficient hole positions when two sample box bodies with different specifications are used in combination.
[0018] In some embodiments, the sample box body is an integrally formed part. By adopting integral forming, the problem of needing to set partition structures on the sample box body due to setting multiple different specifications of sample holes in the sample box body can be avoided, and the space of the sample box body can be utilized more effectively, effectively solving the problem of insufficient hole positions when two sample box bodies with different specifications are used in combination.
[0019] In a second aspect, the present application also provides an automatic sampler, including the sample box structure as described in any one of the above.
[0020] Since the automatic sampler provided in the second aspect includes the sample box structure, the automatic sampler has all the technical effects of the sample box structure, which will not be elaborated here.
[0021] Other features and advantages of the present application will be described in the subsequent description, or, some features and advantages can be inferred from the description or determined without doubt, or can be known by implementing the above technologies of the present application.

[0037] In the field of chromatographic detection, automatic samplers have been gradually promoted and applied due to their convenient and efficient characteristics. To meet the detection requirements under different conditions, there are various sample cartridges available for replacement on one sampler. One can choose to place a large sample cartridge, or two small sample cartridges. There are also sample cartridges that can hold 2-ml sample bottles and those that can hold 5-ml sample bottles, etc.
[0038] However, because there are various types of sample cartridges available for replacement, the identification of sample cartridges has become a problem to be solved. Most of the common automatic samplers on the market currently can be optionally equipped with three small sample cartridges or three large sample cartridges, and the large and small sample cartridges cannot be interchangeably identified.
[0039] In view of this, as Figures 1-6 shown, in a first aspect, an embodiment of the present application provides a sample cartridge structure, including: a sample cartridge assembly 100, including a sample cartridge body 101 and an identification member 102. The sample cartridge body 101 is configured with at least one specification of sample holes, and the sample holes are distributed along a first direction and a second direction, where the first direction is perpendicular to the second direction. The identification member 102 is connected to one side of the sample cartridge body 101 and is located outside the sample cartridge body 101, and the identification member 102 is configured with an identification portion 103 along the first direction and / or the second direction; a detection assembly 200, which is configured with a detection portion, and the detection portion is configured to identify the identification portion 103.
[0040] Exemplarily, the identification member 102 is connected to the sample box body 101. The connection manner between the identification member 102 and the sample box body 101 includes but is not limited to integral molding. The identification member 102 is arranged in a plate shape, and chamfering can be performed at the right-angle position of the identification member 102. The identification portion 103 includes but is not limited to a notch. By arranging the identification portion 103 at different positions of the identification member 102, each position corresponding to a type of sample box body 101, the identification of the sample box assembly 100 is finally realized through the detection of the detection assembly 200.
[0041] The detection assembly 200 includes but is not limited to photoelectric switches. A plurality of groups of photoelectric switches are provided. The photoelectric switches are configured with a groove shape to form the detection portion. One side of the photoelectric switch is the emitting end 203, and the other side is the receiving end 204. When the sample box assembly 100 is not placed on the detection assembly 200, the detection assembly 200 will not detect an occlusion signal, and it is considered that there is no sample box assembly 100. At the same time, at the position of the detection assembly 200 corresponding to the identification portion 103, its signal is not occluded either, while the signals at other positions corresponding to the identification member 102 are occluded, thereby realizing the detection of different specifications of the sample box assembly 100.
[0042] It can be understood that the first direction includes but is not limited to the left-right direction, the second direction includes but is not limited to the front-back direction, and the sample holes are arranged along the first direction and the second direction, so as to form different specifications of the sample box body 101.
[0043] In the above implementation process, the identification member 102 extends out of the outer side of the sample box body 101, and the detection assembly 200 is placed at the identification member 102 for identifying the identification portion 103 of the identification member 102. The type of the sample box assembly 100 can be distinguished by the position and / or quantity of the identification portion 103, etc., thereby solving the problem of identifying the sample box assembly 100, and the identification effect is remarkable.
[0044] As Figure 1 shown, when the sample box body 101 is for double samples, one identification member 102 is provided, and the identification member 102 is provided with one identification portion 103. Through this identification portion 103, the identification of the specification of the sample box body 101 for double samples can be realized, the identification effect is remarkable, and the efficiency is improved.
[0045] Exemplarily, when the sample cartridge body 101 is for double samples, the specifications of the sample cartridge body 101 can be 2 ml, 5 ml, 10 ml, etc. When the detection component 200 detects these three types of double-sample cartridge bodies 101, the identification part 103 can be set at the left, middle, and right positions of the identification member 102, so as to distinguish which specification of the sample cartridge body 101 according to the different signals identified by the detection component 200, and finally realize the identification of the sample cartridge body 101.
[0046] As Figure 2 shown, when the sample cartridge body 101 is for single sample, two identification members 102 are configured. The two identification members 102 are spaced apart and distributed on one side of the sample cartridge body 101, and at least one of the two identification members 102 is configured with the identification part 103. The identification of the specifications of the double-sample cartridge body 101 can be realized through the combination mode of the two identification members 102, with remarkable identification effect and improved efficiency.
[0047] Exemplarily, when the sample cartridge body 101 is for single sample, the specifications of the sample cartridge body 101 can be 2 ml, 4 ml, 5 ml, 10 ml, etc. When the detection component 200 detects these four types of single-sample cartridge bodies 101, two identification members 102 are provided. One of the identification members 102 is not provided with the identification part 103, and it can be determined that the sample cartridge body 101 is for single sample. At the same time, the other identification member 102 can change the position and quantity of the identification part 103. For example, the identification parts 103 of the sample cartridge assemblies 100 of 2 ml, 4 ml, and 5 ml are respectively set at the right, middle, and left positions of the identification member 102, and the quantity of the identification part 103 in these three types of sample cartridge assemblies 100 can be set to only one; of course, the positions of the identification parts 103 corresponding to these three types of sample cartridge assemblies 100 can also be swapped with each other, etc. For the identification part 103 of the 10-ml sample cartridge assembly 100, the quantity can be set to two to make the distinction, and finally the type of the sample cartridge body 101 is judged by the detection component 200.
[0048] It should be noted that for the sample cartridge body 101 for single sample or double samples, the definition of the position of the identification part 103 of each type of sample cartridge assembly 100 is only for example, and does not mean that there is only this one form. As long as the identification and distinction of different types of sample cartridge assemblies 100 can be realized, they all fall within the protection scope of this application.
[0049] As Figure 3As shown, the detection component 200 includes a first detection module 201. The first detection module 201 includes, but is not limited to, three groups of photoelectric switches. The first detection module 201 is configured with a first detection cavity along the first direction, and the first detection cavity is configured to accommodate the identification member 102.
[0050] In the above implementation process, when the identification member 102 is placed in the first detection cavity of the first detection module 201, by setting the identification part 103 of the identification member 102 at different positions, the signals at different positions of the first detection module 201 can be blocked, so as to realize the identification of the specifications of the sample box body 101 of a single sample box or a double sample box. The identification process is simple, the effect is remarkable, and the efficiency is improved.
[0051] Please refer to Figure 3 again. When the sample box body 101 is a single sample, the detection component 200 further includes a second detection module 202. The second detection module 202 includes, but is not limited to, three groups of photoelectric switches. The first detection module 201 and the second detection module 202 are spaced apart and distributed on the sample box body 101, and both the first detection module 201 and the second detection module 202 accommodate the identification member 102.
[0052] In the above implementation process, the sample box body 101 is a single sample, and two identification members 102 are arranged at intervals. One identification member 102 is detected by the first detection module 201, and the other identification member 102 is detected by the second detection module 202. It is possible to detect the identification parts 103 at different positions of the identification member 102 under the combination of the first detection module 201 and the second detection module 202, so as to realize the identification of the single sample box. The identification process is simple, the effect is remarkable, and the efficiency is improved.
[0053] In the prior art, there are no obvious capacity and digit markings on sample trays of different specifications. When getting a sample tray, it is impossible to immediately identify what capacity of sample bottles the sample tray is suitable for and the number of sample bottles that can be placed.
[0054] In view of this, as Figure 4 shown, the sample box body 101 is further configured with an identification part 104, and the identification part 104 includes, but is not limited to, information about the sample holes, such as the size and / or quantity of the sample holes, etc.
[0055] In the above implementation process, through the identification part 104, when the user gets the sample box body 101, the user can quickly identify the capacity of the sample box used by the sample box body 101 and the number of sample bottles that can be placed, saving the user's identification time with remarkable effect. At the same time, setting the identification part 104 on the sample box body 101 will not affect the original structure of the sample box body 101.
[0056] In the prior art, because there is no unified identification regulation for the current square sample box, when describing the position of a certain sample bottle on the sample box, if not described facing the physical object or sample book of this manufacturer, it is very difficult for the other party to understand which position is being described. At the same time, a series of problems are easily caused by understanding ambiguities during use.
[0057] In view of this, as Figure 5 shown, a coordinate system 105 is further configured on the sample box body 101. For example, for the described position (2, 4), the abscissa can be defined as 2 and the ordinate as 4.
[0058] In the above implementation process, by establishing the coordinate system 105 on the sample box body 101, it can be used to solve the problem that the description of the hole position is prone to ambiguity due to the lack of identification of the sample box during use, which is beneficial to the description of the position where the sample bottle is placed on the sample box body 101 and avoids description and understanding errors.
[0059] To meet the daily use requirements, at least six sample boxes are required for an automatic sampler. There are many sample boxes. In the existing sample boxes, a partition structure is generally added in the middle position to divide the sample box into two areas, and each area is used to set different types of sample holes, but this will cause waste of the space of the sample box.
[0060] In view of this, as Figure 6 shown, the sample box body 101 is configured with a first area 106 and a second area 107. The first area 106 and the second area 107 are located on the same side of the sample box body 101, and the first area 106 and the second area 107 are configured to be used to set the sample holes of different specifications. At the same time, in order to accurately describe the position of the sample bottle, corresponding coordinates can be set on the sample box body 101.
[0061] In the above implementation process, by setting sample holes of different specifications in the first area 106 and the second area 107 of the sample box body 101, it can be used to place sample bottles of different specifications, effectively solving the problem of insufficient hole positions when two sample box bodies 101 of different specifications are used in combination.
[0062] In some embodiments, the sample cartridge body 101 is an integrally formed part. By using integral forming, the problem of needing to set partition structures on the sample cartridge body 101 due to setting various sample holes with different specifications on the sample cartridge body 101 can be avoided, and the space of the sample cartridge body 101 can be utilized more effectively, effectively solving the problem of insufficient hole positions when two sample cartridge bodies 101 with different specifications are used in combination.
[0063] In a second aspect, the present application also provides an autosampler, including the sample cartridge structure as described above.
[0064] Exemplarily, during the process of analysis using liquid chromatography or ion chromatography, in order to automatically introduce multiple samples into the flow path in a specified order and enter the chromatographic column, an autosampler is usually used. Compared with manual sampling, the autosampler has the advantages of high efficiency, high repeatability, small volume, preventing contamination, and saving manpower. Using a six-way switching valve and a quantitative sample loop for sampling is currently the most ideal sampling method with high repeatability.
[0065] Generally, an autosampler includes a six-way sampling valve, a sampling syringe, a metering pump, a quantitative loop, etc. The six-way sampling valve is composed of a driving control mechanism such as a motor and a sensor, and an execution mechanism such as a circular gasket (rotor) and a fixed base (stator).
[0066] There are various sampling methods in the autosampler, including full-loop sampling, partial sampling, and non-destructive sampling, etc.
[0067] The full-loop sampling method means sampling with an amount exceeding the volume of the quantitative loop. For example, for a 25ul quantitative loop, full-loop sampling can be performed with a sample of more than 25ul, and the actual volume of the sample entering the chromatographic flow path is the volume of the quantitative loop. (Usually, sampling is performed with 2 - 5 times the volume of the quantitative loop).
[0068] The partial sampling method means that only a part of the volume of the quantitative loop is filled with the sample, generally not exceeding half of the volume of the quantitative loop (laminar flow effect, the flow velocity at the center of the fluid is greater than the flow velocity at the pipe wall). For example, for a 100ul quantitative loop, non-full-loop sampling should be less than 50ul. The sampling volume is determined by the moving position of the syringe.
[0069] The non-destructive sampling method means that only a part of the quantitative loop is filled with the sample, and the rest is supplemented with a filling liquid. This method is mainly used for cases where the sampling volume is very small or the sample is relatively small.
[0070] Since the autosampler provided in the second aspect includes the sample cartridge structure, the autosampler has all the technical effects of the sample cartridge structure, which will not be elaborated here.
[0071] In all embodiments of the present application, "big" and "small" are relative, "many" and "few" are relative, and "up" and "down" are relative. For the expression of such relative terms, the embodiments of the present application will not elaborate further.
[0072] It should be understood that the phrases "in this embodiment", "in the embodiments of the present application", or "as an optional implementation manner" mentioned throughout the specification mean that specific features, structures, or characteristics related to the embodiment are included in at least one embodiment of the present application. Therefore, the phrases "in this embodiment", "in the embodiments of the present application", or "as an optional implementation manner" that appear throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics can be combined in one or more embodiments in any suitable manner. Those skilled in the art should also be aware that the embodiments described in the specification are all optional embodiments, and the actions and modules involved are not necessarily essential to the present application.
[0073] In various embodiments of the present application, it should be understood that the magnitudes of the sequence numbers of the above processes do not necessarily mean the inevitable sequence of execution. The execution sequence of each process should be determined according to its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
[0074] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present application, and all should be covered by the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
