Description

Technical Field

[0001] This application relates to the technical field of ion chromatography. Specifically, it relates to a suppressor with a detection function and an ion chromatograph. Background Art

[0002] The chromatographic suppressor is one of the key components of ion chromatography. In the chemical suppression conductivity detection method, the suppression reaction is an important factor in the high sensitivity and selectivity of ion chromatography, and it is also the main factor that must be considered when selecting a separation column and an eluent. The suppressor mainly plays two roles. One is to reduce the background conductivity of the eluent, and the other is to increase the conductivity value of the ions to be measured.

[0003] In the related art, the traditional suppressor does not have a detection function, resulting in deviations in subsequent measurement results. Summary of the Utility Model

[0004] The purpose of this application is to provide a suppressor with a detection function and an ion chromatograph. The suppressor has a detection function and can improve the accuracy of measurement results.

[0005] In a first aspect, an embodiment of this application provides a suppressor with a detection function, including: a wire group, including a multi-core watertight connector, a first terminal, and a second terminal. The first terminal is connected to the multi-core watertight connector for power supply, and the second terminal is connected to the multi-core watertight connector; a detection component, which is connected to the second terminal to form a detection structure; a fixing structure, which is configured to move relative to the detection structure for fixing the detection structure and / or the wire group.

[0006] In the above implementation process, the first terminal and the second terminal are respectively connected to the multi-core watertight connector. The first terminal is used to supply power to the suppressor. The detection component is connected to the second terminal and fixed by the fixing structure. This can not only realize the utilization of the second terminal and avoid waste of resources, but also when the suppressor is connected to the ion chromatograph, the ion chromatograph and the computer terminal can read the information of the detection component to realize the detection of the suppressor and improve the accuracy of the measurement results.

[0007] In some embodiments, the detection component includes a leak detection tape, and the leak detection tape is welded to the second terminal.

[0008] In the above implementation process, the liquid leakage detection tape is connected to the second terminal. When the suppressor is connected to the ion chromatograph, the ion chromatograph and the computer terminal detect whether the suppressor leaks water by reading the electrical signal of the liquid leakage detection tape. If there is no water leakage, the liquid drops on the liquid leakage detection tape to form an open circuit and there is no electrical signal, then the suppressor is normal; if there is water leakage, the liquid drops on the liquid leakage detection tape to form a short circuit, and there is an electrical signal at this time, then the suppressor leaks water, realizing real-time detection of whether the suppressor leaks water, preventing the suppressor from being used in case of failure, and improving the work efficiency and the stability of the detection value.

[0009] In some embodiments, the liquid leakage detection tape is configured to be flat, and the liquid leakage detection tape is provided with a plurality of detection edges, and the plurality of detection edges are connected in sequence, and the second terminal is connected to at least one of the plurality of detection edges.

[0010] In the above implementation process, the liquid leakage detection tape is provided with a plurality of detection edges, and the detection edges are flat, which can not only increase the area for detecting water leakage, but also prevent the suppressor from being used in case of failure, improve the work efficiency, and at the same time realize the utilization of the second terminal through the liquid leakage detection tape, realizing the reasonable utilization of resources.

[0011] In some embodiments, the detection member includes a temperature probe, and the temperature probe is welded to the second terminal.

[0012] In the above implementation process, the temperature probe is connected to the second terminal. When the suppressor is connected to the ion chromatograph, the ion chromatograph and the computer terminal display the real-time temperature of the suppressor by reading the electrical signal of the temperature probe, so as to determine whether the suppressor is working within a suitable temperature range and improve the stability of the equipment detection value.

[0013] In some embodiments, the suppressor further includes a protective member, and the protective member is disposed at the connection position between the temperature probe and the second terminal.

[0014] In the above implementation process, the protective member is located at the connection position between the temperature probe and the second terminal, which can not only enhance the strength at this position, but also play a waterproof function and improve the safety.

[0015] In some embodiments, the suppressor further includes an inner core, and the fixing structure is movably connected to the inner core, so that the fixing structure and the inner core enclose an avoidance opening, and the avoidance opening is configured for avoidance when the detection structure is fixed.

[0016] In the above implementation process, the fixing structure is connected to the inner core, and after the detection structure passes through the formed avoidance opening, the fixing structure and the inner core can cooperate to fix it, avoiding the detection structure from shaking and other situations, and improving the stability of the detection result.

[0017] In some embodiments, the inner core is provided with a terminal, and the terminal is connected to the first terminal, enabling power supply to the inner core.

[0018] In some embodiments, the fixing structure includes a fixing portion and a connecting portion. The fixing portion is connected to the inner core through the connecting portion. A fixing cavity is arranged on one side of the fixing portion close to the inner core, and the fixing cavity is configured to accommodate the detection structure.

[0019] In the above implementation process, the fixing portion is connected to the connecting portion, and the connecting portion is connected to the inner core, so that the fixing cavity of the fixing portion fixes the detection structure, preventing the detection structure from shaking or the like, enabling real-time detection of the suppressor, and improving the stability of the detection result.

[0020] In some embodiments, the suppressor further includes a housing member, which is provided with a receiving cavity and a wire passing hole. The receiving cavity is configured to accommodate the inner core, the wire passing hole is in communication with the receiving cavity, and the wire passing hole is configured for the wire group to pass through.

[0021] In the above implementation process, the inner core is fixed in the receiving cavity of the housing member, and the first terminal, the second terminal and the detection member are fixed on the inner core, enabling the housing member to protect the inner core, the detection member, the first terminal and the second terminal, and improving the service life of the suppressor; at the same time, the wire group passes through the wire passing hole, so that the first terminal and the second terminal are both located in the receiving cavity, which can not only realize the connection of the wire group to the inner core and the detection member respectively, but also limit the wire group through the wire passing hole, improving the stability of the connection between the first terminal and the inner core and between the second terminal and the detection member.

[0022] In a second aspect, the present application further provides an ion chromatograph, including the suppressor with a detection function as described in any one of the above.

[0023] Since the ion chromatograph provided in the second aspect includes the suppressor with an identification function, the ion chromatograph has all the technical effects of the suppressor with a detection function, which will not be elaborated herein.

[0039] Ion chromatography is a type of high-performance liquid chromatography, so it is also known as high-performance ion chromatography or modern ion chromatography. What differentiates it from traditional ion exchange chromatography columns is mainly that the resin has a very high cross-linking degree and a low exchange capacity, the injection volume is very small, and a plunger pump is used to transport the eluent. Usually, online automatic continuous conductivity detection is performed on the eluate. Separating and determining common anions is the specialty of ion chromatographs. When a sample is injected, the determination results of 7 common ions can be obtained within about 20 minutes, which cannot be achieved by other analytical methods. For the determination of cations, ion chromatography does not show superiority compared with AAS and ICP methods.

[0040] Ion chromatography is mainly used for the analysis of environmental samples, including anions and cations in surface water, drinking water, rainwater, domestic sewage and industrial wastewater, acid depositions, and atmospheric particulate matter, as well as the analysis of trace impurities in water and reagents related to the microelectronics industry.

[0041] In this application, the suppressor uses electrode electrolyzed water to generate H + and OH - , and under the combined action of an electric field and an ion exchange membrane, ion directional migration and exchange are achieved, which can reduce the background conductivity, improve the sensitivity of the ions to be measured, and enable the counterions in the sample to enter the waste liquid.

[0042] However, during the design process, the inventor found that the performance of the suppressor has a great impact on the analysis results. The common fault of the suppressor is liquid leakage. Liquid leakage will reduce the peak area (decrease in sensitivity) and increase the background conductivity. If it is impossible to determine whether there is liquid leakage in the suppressor, when liquid leakage occurs, the measurement results will have serious deviations, and there is no temperature detection set on the suppressor, so it is impossible to determine whether the instrument is operating within a suitable temperature range; all current suppressors use 4-core connectors, but actually only 2 cores are used, and 2 cores are unused, resulting in a waste of resources.

[0043] In view of this, as Figures 1 - 6 shown, in the first aspect, the embodiments of this application provide a suppressor with a detection function, including: a wire group 100, including a multi-core watertight connector 101, a first wiring terminal 102, and a second wiring terminal. The first wiring terminal 102 is connected to the multi-core watertight connector 101 for power supply, and the second wiring terminal is connected to the multi-core watertight connector 101; a detection component 200, which is connected to the second wiring terminal to form a detection structure; a fixing structure 400, which is configured to move relative to the detection structure to fix the detection structure and / or the wire group 100.

[0044] Exemplarily, the suppressor with detection function is applied to an ion chromatograph. The multi-core watertight connector 101 includes but is not limited to a four-core watertight connector. The ion chromatograph is configured with a circuit board. The multi-core watertight connector 101 is connected to the circuit board and can be used for the ion chromatograph to read the information detected by the detector 200.

[0045] In the above implementation process, the first terminal 102 and the second terminal are respectively connected to the multi-core watertight connector 101. The first terminal 102 is used to supply power to the suppressor. The detector 200 is connected to the second terminal and fixed by the fixing structure 400. This can not only make use of the second terminal and avoid wasting resources, but also enable the ion chromatograph and the computer to read the information of the detector 200 after the suppressor is connected to the ion chromatograph, realizing the detection of the suppressor and improving the accuracy of the measurement results.

[0046] As Figure 1 、 Figure 3 and Figure 5 shown, the detector 200 includes a leak detection tape 201, and the leak detection tape 201 is welded to the second terminal. Exemplarily, the suppressor with detection function is generally used vertically. Therefore, the leak detection tape 201 can be located at three positions on the left and right sides and the bottom of the suppressor, increasing the detection area and effectively detecting whether there is leakage.

[0047] In the above implementation process, the leak detection tape 201 is connected to the second terminal. When the suppressor is connected to the ion chromatograph, the ion chromatograph and the computer detect whether the suppressor leaks by reading the electrical signal of the leak detection tape 201. If there is no leakage, the liquid drops on the leak detection tape 201 to form an open circuit and there is no electrical signal, then the suppressor is normal; if there is leakage, the liquid drops on the leak detection tape 201 to form a short circuit, and there is an electrical signal at this time, then the suppressor leaks, realizing real-time detection of whether the suppressor leaks, preventing the suppressor from being used in case of failure, and improving the working efficiency and the stability of the detection value.

[0048] In some embodiments, the leak detection tape 201 is configured to be flat, and the leak detection tape 201 is provided with a plurality of detection edges. For example, there are three detection edges, which are respectively located at three positions on the left and right sides and the bottom of the suppressor. The plurality of detection edges are connected in sequence, and the second terminal is connected to at least one of the plurality of detection edges.

[0049] In the above implementation process, the liquid leakage detection tape 201 is provided with a plurality of detection edges, and the detection edges are flat. This not only increases the area for detecting water leakage but also prevents use in case of a suppressor failure, improving work efficiency. At the same time, the second wiring terminal is utilized through the liquid leakage detection tape 201 to achieve the rational utilization of resources.

[0050] As Figure 2 , Figure 4 and Figure 6 shown, the detection member 200 includes a temperature probe 202. The temperature probe 202 includes, but is not limited to, a thermistor. The temperature probe 202 is welded to the second wiring terminal.

[0051] In the above implementation process, the temperature probe 202 is connected to the second wiring terminal. When the suppressor is connected to the ion chromatograph, the ion chromatograph and the computer terminal display the real-time temperature of the suppressor by reading the electrical signal of the temperature probe 202 to determine whether the suppressor is operating within a suitable temperature range, improving the stability of the equipment detection value.

[0052] In some embodiments, the suppressor further includes a protective member. The protective member includes, but is not limited to, a heat shrink tube. The protective member is disposed at the connection position between the temperature probe 202 and the second wiring terminal.

[0053] In the above implementation process, the protective member is located at the connection position between the temperature probe 202 and the second wiring terminal, which not only enhances the strength at this position but also functions to prevent water, improving safety.

[0054] As Figure 3 and Figure 4 shown, the suppressor further includes an inner core 300. The fixing structure 400 is movably connected to the inner core 300 so that the fixing structure 400 and the inner core 300 enclose an avoidance opening, and the avoidance opening is configured for avoidance when the detection structure is fixed.

[0055] It can be understood that when the detection member 200 is the liquid leakage detection tape 201, in order to improve the stability of the liquid leakage detection tape 201, in addition to being fixed by the fixing structure 400, the side of the liquid leakage detection tape 201 facing away from the inner core 300 can be provided with an adhesive to be pasted on the inner wall of the housing member 500 of the suppressor.

[0056] In the above implementation process, the fixing structure 400 is connected to the inner core 300. After the detection structure passes through the avoidance opening formed by them, the detection structure can be fixed through the cooperation of the fixing structure 400 and the inner core 300, avoiding situations such as shaking of the detection structure and improving the stability of the detection result.

[0057] In some embodiments, the inner core 300 is provided with a terminal 301 , and the terminal 301 is connected to the first terminal 102 to supply power to the inner core 300 .

[0058] In some embodiments, the fixing structure 400 includes a fixing portion 401 and a connecting portion 402, the fixing portion 401 is connected to the inner core 300 through the connecting portion 402, and a fixing cavity is configured on one side of the fixing portion 401 close to the inner core 300, and the fixing cavity is configured to accommodate the detection structure.

[0059] Exemplarily, the fixing portion 401 and the connecting portion 402 may be integrally formed, the fixing portion 401 may be configured as an arc shape, the connecting portion 402 may be configured as a threaded shape on a side away from the fixing portion 401, the inner core 300 may be provided with a fixing hole 302, and the connecting portion 402 may be provided with one end having a thread for threaded connection with the fixing hole 302, so that when the connecting portion 402 is screwed together, the fixing portion 401 may press the detection structure against the inner core 300.

[0060] In another embodiment of the present application, a sliding groove 303 is configured on the inner wall of the inner core 300 or the shell member 500 of the suppressor, and the connecting portion 402 is elastically connected to the sliding groove 303 on the side facing away from the fixed portion 401. For example, the connecting portion 402 and the sliding groove 303 are connected by a reset spring. In actual use, the fixed structure 400 is first slid away from the original position, at which time the reset spring gradually deforms. After the detection structure is placed, the fixed structure 400 is restored to its original position under the action of the reset spring and the detection structure is pressed. When the detection member 200 is a liquid leakage detection belt 201, the fixed structure 400 under this fixing method may be configured with a plurality of them, for example, each detection edge of the liquid leakage detection belt 201 may correspond to at least one fixed structure 400.

[0061] In the above implementation process, the fixing part 401 is connected to the connecting part 402, and the connecting part 402 is connected to the inner core 300, so that the fixing cavity of the fixing part 401 fixes the detection structure to avoid shaking of the detection structure, and the suppressor can be detected in real time to improve the stability of the detection result.

[0062] In some embodiments, the suppressor also includes a shell 500, which is provided with a receiving cavity and a threading hole 503, wherein the receiving cavity is configured to receive the inner core 300, the threading hole 503 is connected to the receiving cavity, and the threading hole 503 is configured to be used for threading the wire group 100.

[0063] Exemplarily, the housing member 500 includes a front housing 501 and a rear housing 502. The front housing 501 is connected to the rear housing 502 to enclose and form the accommodation cavity. At the same time, when the front housing 501 is connected to the rear housing 502, the inner core 300 can be limited and fixed to prevent phenomena such as the movement of the inner core 300 on the housing member 500.

[0064] In the above implementation process, the inner core 300 is fixed in the accommodation cavity of the housing member 500, and the first wiring terminal 102, the second wiring terminal, and the detection member 200 are fixed on the inner core 300, so that the housing member 500 can protect the inner core 300, the detection member 200, the first wiring terminal 102, and the second wiring terminal, and improve the service life of the suppressor. At the same time, the wire group 100 is passed through the wire passing hole 503, so that both the first wiring terminal 102 and the second wiring terminal are located in the accommodation cavity, which can not only realize the connection of the wire group 100 to the inner core 300 and the detection member 200 respectively, but also limit the wire group 100 through the wire passing hole 503 to improve the stability of the connection between the first wiring terminal 102 and the inner core 300 and between the second wiring terminal and the detection member 200.

[0065] In a second aspect, the present application further provides an ion chromatograph, including the suppressor with a detection function as described above.

[0066] Among them, the working process of the ion chromatograph is as follows: the infusion pump transports the mobile phase to the analysis system at a stable flow rate (or pressure). Before the chromatographic column, the sample is introduced through an injector. The mobile phase brings the sample into the chromatographic column. Each component is separated in the chromatographic column and then flows to the conductivity detector with the mobile phase in turn. In a suppressed ion chromatograph, a suppression system is added before the conductivity detector, that is, another high-pressure infusion pump transports the regeneration liquid to the suppressor. In the suppressor, the background conductivity of the mobile phase is reduced, and then the effluent is introduced into the conductivity detection cell, and the detected signal is sent to the data system for recording, processing, or storage.

[0067] Since the ion chromatograph provided in the second aspect includes the suppressor with an identification function, the ion chromatograph has all the technical effects of the suppressor with a detection function, which will not be elaborated here.

[0068] In all embodiments of the present application, "large" and "small" are relative, "many" and "few" are relative, and "upper" and "lower" are relative. For the expression methods of such relative terms, the embodiments of the present application will not be elaborated further.
