Description

Technical Field

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

[0002] Ion chromatography is a type of high-performance liquid chromatography, so it is also called high-performance ion chromatography or modern ion chromatography. The main reason it is different from traditional ion exchange chromatography columns is 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 with online automatic continuous conductivity detection of 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. Regarding the determination of cations, ion chromatography does not show superiority compared with AAS and ICP methods.

[0003] Ion chromatography is mainly used for the analysis of environmental samples, including anions and cations in surface water, drinking water, rainwater, domestic sewage, 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.

[0004] In related technologies, an ion chromatography suppressor is a device used in an ion chromatograph to reduce background conductivity. However, current ion chromatography suppressors do not have an identification function. When the ion chromatography suppressor is used incorrectly, irreversible damage will be caused to it. Summary of the Utility Model

[0005] The purpose of this application is to provide a suppressor with an identification function and an ion chromatograph, which can identify it and avoid irreversible damage caused by incorrect use of the suppressor.

[0006] In a first aspect, an embodiment of this application provides a suppressor with an identification function, including: a wiring harness, which is configured with a multi-core watertight connector, a first wiring terminal, and a second wiring terminal. The first wiring terminal is connected to the multi-core watertight connector for power supply, and the second wiring terminal is connected to the multi-core watertight connector; an identification component, which is connected to the second wiring terminal.

[0007] In the above implementation process, the first wiring terminal is connected to the multi-core watertight connector for power supply of the suppressor. The second wiring terminal is respectively connected to the multi-core watertight connector and the identification component, which can not only realize the utilization of the second wiring 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 identification component and display the suppressor specification model and the suppressor online, preventing incorrect use of the suppressor and invalid operation of the chromatograph without a suppressor.

[0008] In some embodiments, the identification component includes an identification resistor, and the identification resistor is soldered to the second terminal.

[0009] In the above implementation process, the identification resistor is connected to the second terminal. When the suppressor is connected to the ion chromatograph, the ion chromatograph and the computer can read the voltage value of the divided voltage of the identification resistor and display the suppressor specification model and whether the suppressor is online, thereby preventing incorrect use of the suppressor and invalid operation of the chromatograph without a suppressor.

[0010] In some embodiments, the suppressor further includes a protective component, and the protective component is disposed at the connection position between the identification resistor and the second terminal.

[0011] In the above implementation process, by providing a protective component at the connection position between the identification resistor and the second terminal, not only can the strength at this connection position be ensured, but also a waterproof function can be achieved, improving safety.

[0012] In some embodiments, the identification component includes a memory chip, and the memory chip is soldered to the second terminal.

[0013] In the above implementation process, the model of the suppressor is preset in the memory chip. By directly reading the start time of use and the model of use through the ion chromatograph and the computer, the chromatograph and the computer automatically accumulate and record the use time, which is convenient for accurately calculating the life of the suppressor, and at the same time can also prevent incorrect use of the suppressor and invalid operation of the ion chromatograph without a suppressor.

[0014] In some embodiments, the suppressor further includes a waterproof colloid, and the waterproof colloid coats the second terminal and the memory chip.

[0015] In the above implementation process, the second terminal and the memory chip can be completely encapsulated and cured by the waterproof colloid, which can not only ensure a certain strength, but also play a waterproof function, improving safety.

[0016] In some embodiments, the suppressor further includes an inner core, and the inner core is provided with a terminal post and a fixing hole. The terminal post is connected to the first terminal, and the fixing hole is configured to fix the identification component.

[0017] In the above implementation process, the inner core is connected to the first terminal through the terminal post to realize the power supply of the inner core. At the same time, the identification component is fixed on the inner core through the fixing hole, which can prevent the shaking of the second terminal and the identification component and ensure the stability during the use of the suppressor.

[0018] In some embodiments, the suppressor further includes a fixing member and a connecting member. The connecting member passes through the fixing member and is connected to the fixing hole.

[0019] In the above implementation process, the connecting member fixes the fixing member on the inner core. The fixing member can be used to fix the second wiring terminal and the identification member, and can prevent the second wiring terminal and the identification member from shaking.

[0020] In some embodiments, the suppressor further includes a housing member. The housing member is configured with a receiving cavity, and the receiving cavity is configured to receive the inner core.

[0021] In the above implementation process, the inner core is fixed in the receiving cavity of the housing member, and the first wiring terminal, the second wiring terminal, and the identification member are fixed on the inner core, so that the housing member can protect the inner core, the identification member, the first wiring terminal, and the second wiring terminal, and improve the service life of the suppressor.

[0022] In some embodiments, one end of the housing member is further configured with a wire passing hole, and the wire passing hole is configured to allow the wiring wire group to pass through, so that the first wiring terminal and the second wiring terminal are located in the receiving cavity.

[0023] In the above implementation process, the wiring wire group passes through the wire passing hole, so that both the first wiring terminal and the second wiring terminal are located in the receiving cavity. This can not only realize the connection between the wiring wire group and the inner core and the identification member respectively, but also limit the wiring wire group through the wire passing hole, and improve the stability of the connection between the first wiring terminal and the inner core and between the second wiring terminal and the identification member.

[0024] In a second aspect, the present application further provides an ion chromatograph, including the suppressor with an identification function as described in any one of the above.

[0025] 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 an identification function, which will not be elaborated here.

Detailed implementation manners

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can usually be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application to be protected, but only represents the selected embodiments of the present application.

These terms are mainly used to better describe this application and its embodiments, and are not used to limit that the indicated devices, elements, or components must have a specific orientation, or be constructed and operated in a specific orientation.

[0037] Moreover, in addition to being used to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to the specific circumstances.

[0038] In addition, the terms "installed", "set up", "provided with", "connected", "linked" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or a point connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is internal communication between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0039] In addition, terms such as "first", "second", etc. are mainly used to distinguish different devices, elements, or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements, or components. Unless otherwise specified, the meaning of "a plurality" is two or more. Embodiment

[0040] In this application, the suppressor uses electrodes to electrolyze water to generate H + and OH - , and under the combined action of an electric field and an ion exchange membrane, the directional migration and exchange of ions are realized, the background conductance can be reduced, the sensitivity of the ions to be measured can be improved, and the counter ions in the sample can enter the waste liquid.

[0041] However, the inventor found during the design process that the suppressor only has positive and negative identification plates. If the identification plate falls off, it is impossible to distinguish whether the suppressor is a negative suppressor or a positive suppressor; in case the suppressor is used incorrectly, it will cause irreversible damage to the suppressor. At the same time, the wire connectors of suppressors from various manufacturers are of a common type, resulting in not knowing how long the suppressor has been used after replacing it. When used again, it is already aged, seriously affecting the test efficiency; the current suppressors all use 4-core connectors, but actually only 2 cores are used, and 2 cores are unused, causing waste of resources.

[0042] In view of this, as Figures 1 - 4 shown, in a first aspect, an embodiment of the present application provides a suppressor with an identification function, including: a wiring harness 100, which is configured with 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; an identification component 200, which is connected to the second wiring terminal.

[0043] Exemplarily, the suppressor with an identification 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 identified by the identification component 200.

[0044] In the above implementation process, the first wiring terminal 102 is connected to the multi-core watertight connector 101 for power supply of the suppressor. The second wiring terminal is respectively connected to the multi-core watertight connector 101 and the identification component 200, which can not only realize the utilization of the second wiring terminal and avoid resource waste, but also when the suppressor is connected to the ion chromatograph, the ion chromatograph and the computer terminal can read the information of the identification component 200 and display the suppressor specification model and whether the suppressor is online, preventing the situation of incorrect use of the suppressor and invalid operation of the chromatograph without a suppressor.

[0045] As Figures 1 - 4 shown, the identification component 200 includes an identification resistor 201, and the identification resistor 201 is welded to the second wiring terminal.

[0046] Exemplarily, the ion chromatograph and the computer terminal set different preset voltage values and correspond them to different models of suppressors. For example, when the voltage value is 0.455V, it is displayed as a cation suppressor;

[0047] For example, voltage VCC = 5V, resistance Ra (internal component of the ion chromatograph) = 10KΩ, resistance Rb (identification resistor 201) = 1KΩ, voltage detection V = VCC*Rb / (Ra + Rb) = 0.455V; at this time, the chromatograph and the computer terminal display that the specification model of the suppressor is a cation suppressor.

[0048] The chromatograph and the computer terminal set different preset voltage values and correspond them to different models of suppressors. For example, when the voltage value is 1.667V, it is displayed as an anion suppressor.

[0049] For example, when the voltage VCC = 5V, the resistor Ra = 10KΩ, the resistor Rb = 5KΩ, the voltage detection V = VCC * Rb / (Ra + Rb) = 1.667V; at this time, the chromatograph and the computer terminal display that the suppressor display specification model is a negative suppressor.

[0050] The chromatograph and the computer terminal preset different voltage values and correspond them to different models of suppressors. For example, when the voltage value is 5V, it is displayed as no suppressor installed.

[0051] For example, if no suppressor is installed, the resistor Rb is infinite, and the voltage detection V = VCC * Rb / (Ra + Rb) = 5V; at this time, the chromatograph and the computer terminal display that no suppressor is installed.

[0052] In the above implementation process, the identification resistor 201 is connected to the second terminal. When the suppressor is connected to the ion chromatograph, the ion chromatograph and the computer terminal can read the voltage value divided by the identification resistor 201 and display the suppressor specification model and whether the suppressor is online, thus preventing the situation of incorrect use of the suppressor and invalid operation of the ion chromatograph without a suppressor.

[0053] In some embodiments, the suppressor further includes a protective member, and the protective member includes but is not limited to a heat shrinkable tube, and the protective member is disposed at the connection position between the identification resistor 201 and the second terminal.

[0054] In the above implementation process, by setting a protective member at the connection position between the identification resistor 201 and the second terminal, not only can the strength at this connection position be ensured, but also the waterproof function can be achieved, improving the safety.

[0055] As Figure 5 shown, the identification member 200 includes a memory chip 202, and the memory chip 202 is welded to the second terminal.

[0056] In the above implementation process, the model of the suppressor is preset in the memory chip 202. By directly reading the start time of use and the model of use through the ion chromatograph and the computer terminal, the ion chromatograph and the computer terminal automatically accumulate and record the use time, which is convenient for accurately calculating the life of the suppressor, and at the same time can also prevent the situation of incorrect use of the suppressor and invalid operation of the ion chromatograph without a suppressor.

[0057] As Figure 5 shown, the suppressor further includes a waterproof colloid 203, and the waterproof colloid 203 covers the second terminal and the memory chip 202.

[0058] In the above implementation process, the second terminal and the memory chip 202 can be completely encapsulated and cured by the waterproof colloid 203, which can not only ensure a certain strength, but also play a waterproof function, improving the safety performance.

[0059] As Figures 1 - 2 shown, the suppressor further includes an inner core 300, which is configured with a terminal 301 and a fixing hole 302. The terminal 301 is connected to the first terminal 102, and the fixing hole 302 is configured to fix the identification member 200.

[0060] In the above implementation process, the inner core 300 is connected to the first terminal 102 through the terminal 301 to supply power to the inner core 300. At the same time, the identification member 200 is fixed on the inner core 300 through the fixing hole 302, which can prevent the second terminal and the identification member 200 from shaking and ensure the stability during the use of the suppressor.

[0061] In some embodiments, the suppressor further includes a fixing member 400 and a connecting member 500. The connecting member 500 passes through the fixing member 400 and is connected to the fixing hole 302. Exemplarily, the fixing member 400 includes but is not limited to a fixing seat, and the connecting member 500 includes but is not limited to a screw. The fixing member 400 is configured in a semi-circular saddle shape, and the semi-circle can exactly fit the diameter of the wiring harness 100. Of course, the fixing member 400 can also be set in other shapes, such as square, etc., as long as it can fix the wiring harness 100. Through the cooperation of the fixing member 400 and the connecting member 500, not only can the shaking be prevented, but also the second terminal and the identification member 200 can be prevented from being pulled when the external wiring harness 100 is stretched.

[0062] In the above implementation process, the connecting member 500 fixes the fixing member 400 on the inner core 300, and the fixing member 400 can be used to fix the second terminal and the identification member 200, preventing the second terminal and the identification member 200 from shaking.

[0063] Please refer to Figure 1 and Figure 2 again. The suppressor further includes a housing member 600, which is configured with a receiving cavity for receiving the inner core 300. Exemplarily, the housing member 600 includes a front housing 601 and a rear housing 602. The front housing 601 is connected to the rear housing 602 to enclose the receiving cavity. At the same time, when the front housing 601 is connected to the rear housing 602, the inner core 300 can be limited and fixed to prevent the inner core 300 from moving on the housing member 600.

[0064] In the above implementation process, the inner core 300 is fixed in the accommodation cavity of the housing member 600, and the first wiring terminal 102, the second wiring terminal, and the identification member 200 are fixed on the inner core 300, so that the housing member 600 can protect the inner core 300, the identification member 200, the first wiring terminal 102, and the second wiring terminal, and improve the service life of the suppressor.

[0065] In some embodiments, one end of the housing member 600 is further provided with a wire passing hole 603, and the wire passing hole 603 is configured to allow the wiring wire group 100 to pass through, so that the first wiring terminal 102 and the second wiring terminal are located in the accommodation cavity.

[0066] In the above implementation process, the wiring wire group 100 passes through the wire passing hole 603, so that both the first wiring terminal 102 and the second wiring terminal are located in the accommodation cavity. This can not only realize the connection of the wiring wire group 100 to the inner core 300 and the identification member 200 respectively, but also limit the wiring wire group 100 through the wire passing hole 603, and improve the connection stability between the first wiring terminal 102 and the inner core 300 and between the second wiring terminal and the identification member 200.

[0067] In a second aspect, the present application further provides an ion chromatograph, including the suppressor with an identification function as described above.

[0068] 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 carries the sample into the chromatographic column. Each component is separated in the chromatographic column and then flows to the conductivity detector in sequence with the mobile phase. In suppressed ion chromatography, 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.

[0069] Since the ion chromatograph provided in the second aspect includes a suppressor with an identification function, the ion chromatograph has all the technical effects of the suppressor with an identification function, which will not be elaborated here.

[0070] 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 elaborate further.
