[0002] With the development of control engineering technology, a sample pretreatment platform has emerged that uses chromatography-mass spectrometry (GC-MS) injection technology. This technology enables multiple GC-MS instruments to analyze samples using different injection methods.

[0003] In traditional techniques, it usually takes ten to several tens of minutes to analyze a sample by chromatography-mass spectrometry. The time for the injector to complete the injection of a sample is about three to five minutes. Therefore, when analyzing samples by chromatography-mass spectrometry, the injector is idle and waiting most of the time.

[0004] However, currently, a single sample pretreatment platform can only inject samples for one chromatography-mass spectrometer, resulting in low injector efficiency and wasted resources. Summary of the Invention

[0005] Therefore, it is necessary to provide a sample injection control method, device, computer equipment, computer-readable storage medium, and computer program product that can simultaneously inject samples from multiple chromatography-mass spectrometers using a single sample pretreatment platform, thereby improving the efficiency of sample injector usage, in order to address the aforementioned technical problems.

[0013] In one embodiment, the control device further includes a set of serial interfaces; the serial interfaces are used to replace the faulty output interface when any output interface of the control device fails.

[0014] Secondly, this application also provides a sample injection control device, comprising:

[0016] The sample aspiration module is used to aspirate samples from each chromatography-mass spectrometer and inject them into each of the chromatography-mass spectrometers.

[0017] The second signal transmitting module is used to send an injection completion signal to the control device after the sample injection to each of the chromatography-mass spectrometers is completed; the control device is used to respond to the injection completion signal and send a second running signal to each of the chromatography-mass spectrometers through the multiple output interfaces to control each of the chromatography-mass spectrometers to enter the sample analysis state.

[0018] Thirdly, this application also provides a control device, characterized in that the control device includes multiple output interfaces and one input interface, the input interface being connected to a pretreatment injection platform circuit, and the multiple output interfaces being respectively connected to a chromatography-mass spectrometer circuit; the control device is used to receive ready signals from multiple chromatography-mass spectrometers sent by the pretreatment injection platform through the input interface, and in response to each ready signal, to send a first running signal to each chromatography-mass spectrometer through the multiple output interfaces to control each chromatography-mass spectrometer to enter a pre-running state; the ready signal is sent by the pretreatment injection platform when it determines that multiple chromatography-mass spectrometers are in a ready state; the control device is also used to receive an injection completion signal sent by the pretreatment injection platform through the input interface, and in response to the injection completion signal, to send a second running signal to each chromatography-mass spectrometer through the multiple output interfaces to control each chromatography-mass spectrometer to enter a sample analysis state; the injection completion signal is sent by the pretreatment injection platform after completing sample injection into each chromatography-mass spectrometer.

[0019] Fourthly, this application also provides a computer device, the computer device including a memory and a processor, the memory storing a computer program, and the processor executing the computer program to implement the sample injection control of the method described in any one of the embodiments of this application.

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0033] The sample injection control method provided in this application embodiment can be applied to, for example, Figure 1 In the application environment shown, the sample pretreatment platform 102 communicates with multiple chromatography-mass spectrometers via a control device 104. First, upon determining that the multiple chromatography-mass spectrometers are in a ready state, the sample pretreatment platform 102 sends ready signals from the multiple chromatography-mass spectrometers to the control device 104. The control device 104, in response to each ready signal, sends a first running signal to each chromatography-mass spectrometer through multiple output interfaces to control each chromatography-mass spectrometer to enter a pre-running state. Then, samples are aspirated from each chromatography-mass spectrometer and injected into each spectrometer. Finally, after completing sample injection into each chromatography-mass spectrometer, an injection completion signal is sent to the control device 104. The control device 104, in response to the injection completion signal, sends a second running signal to each chromatography-mass spectrometer through multiple output interfaces to control each chromatography-mass spectrometer to enter the sample analysis state.

[0034] In one exemplary embodiment, such as Figure 2 As shown, a sample injection control method is provided, which can be applied to... Figure 1 The following steps are used as an example of the pretreatment sample introduction platform 102, including steps 202 to 206. Wherein:

[0035] Step 202: After determining that multiple chromatography-mass spectrometers are in a ready state, send a ready signal of the multiple chromatography-mass spectrometers to the control device; the control device is used to respond to each ready signal and send a first running signal to each chromatography-mass spectrometer through multiple output interfaces to control each chromatography-mass spectrometer to enter the pre-running state.

[0036] In this context, the control equipment refers to the central control device or system used to control and manage multiple chromatography-mass spectrometers, typically including a computer or controller. Determining that multiple chromatography-mass spectrometers are in a ready state means that they are prepared to proceed to the next step of the operation. The first operating signal refers to the signal that controls each chromatography-mass spectrometer to enter the pre-operation state, i.e., ready to begin sample analysis. The pre-operation state refers to the state the chromatography-mass spectrometer enters after receiving the first operating signal, including self-testing, calibration, and preparation.

[0037] Specifically, the sample pretreatment platform first confirms that multiple chromatography-mass spectrometers have completed self-tests and preparations and are ready to begin sample analysis. It then sends a ready signal to the control device, indicating the readiness status of each spectrometer, so that the control device can proceed with subsequent operations. Next, the control device responds to the ready signals; upon receiving the ready signals from each spectrometer, it takes corresponding actions. Finally, the control device sends a first operating signal to each spectrometer through multiple output interfaces, initiating pre-operation.

[0038] Step 204: Samples from each chromatography-mass spectrometer are aspirated and injected into each of the aforementioned chromatography-mass spectrometers.

[0039] Specifically, in the pre-running state, each chromatography-mass spectrometer is ready to receive samples. Samples can be extracted from the sample container by aspiration and injected into each chromatography-mass spectrometer.

[0040] Step 206: After completing the sample injection for each chromatography-mass spectrometer, an injection completion signal is sent to the control device. The control device is used to respond to the injection completion signal by sending a second operating signal to each chromatography-mass spectrometer through multiple output interfaces to control each chromatography-mass spectrometer to enter the sample analysis state.

[0041] Sample injection refers to introducing the sample to be analyzed into the injection port or system of the chromatography-mass spectrometer for subsequent analysis and detection. The second operating signal controls each chromatography-mass spectrometer to enter sample analysis mode, i.e., to begin analyzing and detecting the sample. Sample analysis mode refers to the state the chromatography-mass spectrometer enters after receiving the second operating signal, including processes such as sample separation, detection, and data acquisition.

[0042] Specifically, after each chromatography-mass spectrometer completes sample injection, the sample pretreatment platform sends an injection completion signal to the control device. Upon receiving the injection completion signal, the control device responds accordingly. Finally, the control device sends a second operating signal to each chromatography-mass spectrometer through multiple output interfaces, instructing them to enter sample analysis mode and begin sample analysis and detection.

[0043] In the above-described sample injection control method, firstly, after confirming that multiple chromatography-mass spectrometers are in a ready state, a ready signal for each of the multiple chromatography-mass spectrometers is sent to the control device. The control device, in response to each ready signal, sends a first operating signal to each chromatography-mass spectrometer through multiple output interfaces to control each chromatography-mass spectrometer to enter a pre-operation state. Then, samples are aspirated from each chromatography-mass spectrometer and injected into each of the spectrometers. Finally, after completing the sample injection into each chromatography-mass spectrometer, an injection completion signal is sent to the control device. The control device, in response to the injection completion signal, sends a second operating signal to each chromatography-mass spectrometer through multiple output interfaces to control each chromatography-mass spectrometer to enter the sample analysis state. By sending confirmation messages about the readiness of multiple chromatography-mass spectrometers to the control device, the pre-operation status of each chromatography-mass spectrometer is initiated. Then, the sample is injected into each chromatography-mass spectrometer, and the injection information is sent to the control device. This allows the control device to promptly control each chromatography-mass spectrometer to enter the sample analysis state, enabling a single sample pretreatment platform to simultaneously inject samples from multiple chromatography-mass spectrometers, thus improving the efficiency of the injectors.

[0044] In one embodiment, the sample injection control method further includes:

[0045] Step 1: Receive the operating status information of each chromatography-mass spectrometer returned by the control equipment.

[0046] The operating status information refers to the current status of the chromatography-mass spectrometer, which can include real-time monitoring data of parameters such as the working status, temperature, pressure, and flow rate of the chromatography-mass spectrometer. The control equipment can obtain the current operating status of each chromatography-mass spectrometer by analyzing and processing this information.

[0047] Step 2: Based on the operating status information, determine whether each chromatography-mass spectrometer is in a ready state.

[0048] Specifically, the ready state means that the chromatography-mass spectrometer has completed initialization, the temperature and pressure have stabilized, and all components and systems are functioning normally.

[0049] In this embodiment, by monitoring and judging the operating status of the chromatography-mass spectrometer through control equipment, it is possible to ensure that sample analysis is performed at the appropriate time, realize intelligent management and control of the chromatography-mass spectrometer, and improve the efficiency and performance of the entire system.

[0050] In one embodiment, sending readiness signals for multiple chromatography-mass spectrometers to a control device includes:

[0051] Scenario 1: Simultaneously sending ready signals from multiple chromatography-mass spectrometers to the control equipment.

[0052] Simultaneous transmission refers to the process where the sample pretreatment platform can send a ready signal to the control device when the current sample pretreatment platform determines that multiple chromatography-mass spectrometers are in a ready state.

[0053] Specifically, after receiving the ready signals from multiple chromatography-mass spectrometers, the control equipment can immediately proceed to the next step, such as sending the first run signal to each chromatography-mass spectrometer to start sample analysis.

[0054] Scenario 2: Sequentially send ready signals from multiple chromatography-mass spectrometers to the control equipment.

[0055] In this context, sequential transmission refers to the pretreatment injection platform sending the readiness signals of each chromatography-mass spectrometer to the control device in a specific order.

[0056] For example, a priority order is set, where the chromatograph-mass spectrometer that sends its ready signal first in the sample pretreatment platform has a higher priority, and the chromatograph-mass spectrometer that sends its ready signal later has a lower priority. When the control device receives the first ready signal, it will perform the corresponding operation and then wait to receive the next ready signal, thereby controlling the operation of each chromatograph-mass spectrometer in sequence.

[0057] In this embodiment, by simultaneously or sequentially sending readiness signals from multiple chromatography-mass spectrometers to the control device, the transmission and reception of readiness signals from multiple chromatography-mass spectrometers are achieved. This ensures that the control device proceeds to the next step only after all chromatography-mass spectrometers are in a ready state, thereby improving the overall efficiency and accuracy of the system.

[0058] In one embodiment, the sample injection control method further includes:

[0059] Step 1: After completing the sample injection for any one of the chromatography-mass spectrometers, send an injection completion signal to the control device.

[0060] Specifically, the injection completion signal can be sent to the control device via the pretreatment injection platform. After receiving the injection completion signal, the control device will perform corresponding processing and judgment.

[0061] Step 2: The above-mentioned control device is used to respond to the injection completion signal by sending a second operating signal to any one of the chromatographs / mass spectrometers through the corresponding output interface, so as to control any one of the chromatographs / mass spectrometers to enter the sample analysis state.

[0062] Specifically, according to the operating procedures and experimental requirements, the control equipment sends a second operating signal to any one of the chromatography-mass spectrometers, starting the chromatography-mass spectrometer to begin analyzing the sample.

[0063] In the above embodiments, intelligent control of the chromatography-mass spectrometer is achieved by sending and receiving control signals. The control device can determine the operating status of each chromatography-mass spectrometer based on the injection completion signal, and send corresponding operating signals according to experimental requirements to control the chromatography-mass spectrometer to perform sample analysis. This ensures that the sample is analyzed in a timely manner after injection, improving the efficiency and accuracy of the system.

[0064] In one embodiment, the control device further includes a set of serial interfaces; the serial interfaces are used to replace the faulty output interface when any output interface of the control device fails.

[0065] In this embodiment, by reserving an additional set of interfaces, when the original contact closure fails or other problems occur, this set of backup interfaces can be used to send operation signals to ensure the normal operation of the equipment, thereby enhancing the reliability and stability of the equipment.

[0066] In one exemplary embodiment, such as Figure 3 As shown, a control device is provided, comprising multiple output interfaces and one input interface. The input interface is connected to a sample pretreatment injection platform circuit, and the output interface is connected to a chromatography-mass spectrometer circuit. The control device is configured to receive readiness signals from multiple chromatography-mass spectrometers sent by the sample pretreatment injection platform via the input interface, and in response to each readiness signal, send a first operating signal to each chromatography-mass spectrometer via the multiple output interfaces to control each chromatography-mass spectrometer to enter a pre-operation state. The readiness signals are sent by the sample pretreatment injection platform when it determines that multiple chromatography-mass spectrometers are in a readiness state. The control device is also configured to receive an injection completion signal from the sample pretreatment injection platform via the input interface, and in response to the injection completion signal, send a second operating signal to each chromatography-mass spectrometer via the multiple output interfaces to control each chromatography-mass spectrometer to enter a sample analysis state. The injection completion signal is sent by the sample pretreatment injection platform after completing sample injection into each chromatography-mass spectrometer.

[0067] In the above embodiments, multiple output interfaces allow for the simultaneous control of multiple chromatography-mass spectrometers, improving analytical efficiency and sample processing capabilities. Input interfaces enable the control device to receive ready and injection completion signals from the pretreatment injection platform, facilitating information exchange with the platform. The control device also responds promptly to these signals, ensuring that the chromatography-mass spectrometers enter pre-running and sample analysis states at appropriate times. Multiple output interfaces allow the control device to send first and second running signals to each chromatography-mass spectrometer, enabling independent control and operation of each instrument, improving sample analysis efficiency and accuracy, and achieving collaborative and automated operation of multiple chromatography-mass spectrometers.

[0068] In one embodiment, to facilitate understanding of the embodiments of this application by those skilled in the art, the following description will take the example of a control device including one input interface and two output interfaces.

[0069] refer to Figure 4 and Figure 5 The diagrams show the external and internal structures of the control device, respectively. Figure 4 As shown, the control device includes one input interface 41 and two output interfaces, namely a first output interface 42 and a second output interface 43. The input interface 41 is connected to the sample pretreatment platform circuit and is used to receive signals sent by the sample pretreatment platform. The first output interface 42 is connected to the first chromatography-mass spectrometer and is used to send operating signals to the first chromatography-mass spectrometer. The second output interface 43 is connected to the second chromatography-mass spectrometer and is used to send operating signals to the second chromatography-mass spectrometer.

[0070] Specifically, such as Figure 6 As shown, application Figure 4 The sample injection control method of the control device shown includes the following steps:

[0071] Step 602: The sample pretreatment platform confirms that multiple chromatography-mass spectrometers are in a ready state.

[0072] Specifically, the signal trigger line of the interface (interface signal, which refers to the signal used for communication and data transmission between different hardware devices in a computer system, and can be an electrical signal, optical signal or wireless signal) of the sample pretreatment platform is connected to the wiring port of the control device, and the chromatogram 1 interface (i.e. the first output interface) and chromatogram 2 interface (i.e. the second output interface) in the control device are connected to the first chromatogram-mass spectrometer and the second chromatogram-mass spectrometer, respectively.

[0073] Step 604: The sample pretreatment platform sends ready signals from multiple chromatography-mass spectrometers to the control device, which then converts one set of synchronization signals into two sets of synchronization signals.

[0074] The pretreatment injection platform consists of a set of synchronization signals, which are composed of a set of input signals (TTL-In digital I / O, 5V) and two sets of output signals (SWOut-1 / SWOut-2 contact closure). The input signal (TTL-In digital I / O, 5V) is used to receive the ready signal from the chromatography-mass spectrometer.

[0075] Specifically, after the control equipment connects to a single set of synchronization signals from the pretreatment sample injection platform, it converts one set of synchronization signals into two sets of synchronization signals.

[0076] Step 606: In response to each ready signal, the control device sends the first running signal to each chromatography-mass spectrometer through multiple output interfaces, thereby controlling each chromatography-mass spectrometer to enter the pre-running state.

[0077] Specifically, after the sample pretreatment platform receives the chromatogram and mass spectrometer ready status, it sends out the SWOut-2 signal to put the chromatogram and mass spectrometer into the pre-running state.

[0078] Step 608: The sample pretreatment platform picks up samples from multiple chromatography-mass spectrometers, injects them into the multiple chromatography-mass spectrometers, sends an injection completion signal to the control device, sends a second running signal to each chromatography-mass spectrometer, and controls each chromatography-mass spectrometer to enter the sample analysis state.

[0079] Specifically, the sample preparation platform begins the sample preparation process, cleans the injection needle, aspirates the sample and injects it into the chromatography-mass spectrometer. After the injection is completed, it sends an injection completion signal to the control device. In response to the injection completion signal, the control device sends a second running signal to each chromatography-mass spectrometer to trigger the operation of the chromatography-mass spectrometer.

[0080] The control device connects to the pretreatment injection platform to split its synchronization signal. Specifically, one set of input signals (TTL-In digital I / O, 5V) from the pretreatment injection platform is output by the control device's logic circuit as two sets of input signals (TTL-In-1, TTL-In-2 digital I / O, 5V). The two sets of output signals SWOut-1 / SWOut-2 from the pretreatment injection platform are closed, and the control device's logic circuit outputs four sets of output signals SWOut-1 / SWOut-2, SWOut-3 / SWOut-4, with the contacts closed. The pretreatment injection platform's synchronization signal is connected to the control device's interface port, and the two sets of synchronization signals are output from the control device's Chromatography 1 and Chromatography 2 interfaces, respectively. The Chromatography 1 interface output signal is connected to the first chromatography-mass spectrometer, and the Chromatography 2 interface output signal is connected to the second chromatography-mass spectrometer. The control device is powered by a 24V power supply, which, after voltage conversion, outputs a 5V TTL-In signal. By ensuring that one set of TTL-In signals is split into two groups, the voltage and current are stable, and the triggering is stable. In addition, an extra DB9 (serial communication interface) interface needs to be reserved to provide two contact closures for backup.

[0081] In this embodiment, a single set of synchronization signals from the pretreatment injection platform is connected to a control device. The control device then splits this single set of synchronization signals into two sets, which are connected to multiple chromatography-mass spectrometers (GC-MS). The GC-MS operating status is read in real-time and fed back to the pretreatment injection platform. Upon receiving the GC-MS's ready status signal, the pretreatment injection platform first sends a ready signal to the control device. The control device then sends a first operating signal to each GC-MS. Simultaneously, the pretreatment injection platform picks up samples from each GC-MS and injects them into each GC-MS. After injection, it sends an injection completion signal to the control device, which then sends a second operating signal to each GC-MS, triggering the GC-MS to run. This method, by constructing a control device that acts as a communication relay between the pretreatment injection platform and the GC-MS, enables injection control for at least two GC-MS, overcoming the shortcomings of traditional methods that can only inject samples for one GC-MS, resulting in low injector efficiency and wasted resources.

[0082] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0083] In one embodiment, such as Figure 7 As shown, based on the same inventive concept, this application also provides a sample injection control device for implementing the sample injection control method described above. It includes: a first signal transmitting module 701, a sample aspiration module 702, and a second signal transmitting module 703, wherein:

[0084] The first signal transmitting module 701 is used to send readiness signals of multiple chromatography-mass spectrometers to the control device when it is determined that multiple chromatography-mass spectrometers are in a ready state; the control device is used to respond to each readiness signal and send a first running signal to each chromatography-mass spectrometer through multiple output interfaces to control each chromatography-mass spectrometer to enter the pre-running state.

[0085] The sample aspiration module 702 is used to aspirate samples from each chromatography-mass spectrometer and inject them into each chromatography-mass spectrometer.

[0086] The second signal transmitting module 703 is used to send an injection completion signal to the control device after the sample injection to each chromatography-mass spectrometer is completed; the control device is used to respond to the injection completion signal and send a second running signal to each chromatography-mass spectrometer through multiple output interfaces to control each chromatography-mass spectrometer to enter the sample analysis state.

[0087] In one embodiment, the first signal transmitting module 701 is further configured to receive the operating status information of each chromatography-mass spectrometer returned by the control device; and determine whether each chromatography-mass spectrometer is in a ready state based on the operating status information.

[0090] In one embodiment, the first signal transmitting module 701 is further configured to control the device to reserve an additional set of interfaces for contact closure during the transmission of the first and second running signals.
