Description

Technical Field

[0001] The utility model relates to the technical field of ion chromatographs, in particular to an ion chromatograph with temperature control. Background Art

[0002] A chromatograph is a device used for chromatographic separation and analysis, including an injection system, a detection system, a recording and data processing system, a temperature control system, and a mobile phase control system. Modern chromatographs are characterized by stability, sensitivity, versatility, and a high degree of automation. An ion chromatograph is a type of high performance liquid chromatography, so it is also called high performance ion chromatography (HPIC) or modern ion chromatography. It differs from traditional ion exchange column chromatography mainly in that the resin has a high degree of cross-linking and a low exchange capacity, the injection volume is very small, and the eluent is delivered by a plunger pump. The eluent is usually subjected to online automatic continuous conductivity detection.

[0003] The existing ion chromatograph adopts passive heat dissipation when in use. When the ion chromatograph is working continuously, the heat cannot be discharged in time, which will cause the internal instrument temperature of the ion chromatograph to rise, affecting the performance of the ion chromatograph. In addition, in a low temperature environment, the temperature cannot be adjusted in the device. In order to solve the shortcomings of the existing technology, we propose an ion chromatograph with temperature control. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Embodiment 1, as Figure 1-4 As shown, an ion chromatograph with temperature control, the chromatograph host can perform flow separation detection on liquids, fix the raw liquid to be detected on the fixed plate 24 inside the sample injector 13, and support the test tube by connecting the test tube to the mounting groove 25 on the surface of the fixed plate 24. The sample injector 13 transfers the detection raw liquid to the quantitative ring 11, and the quantitative ring 11 performs a quantitative process. The second guide tube 9 connected to the outer surface of the quantitative ring 11 can be transported to the chromatograph host 1 to perform a detection process. After the chromatograph host 1 is injected by the sample injector 13, the pressure pump 16 provided in the detection chamber 15 can inject the sample into the separation column for a separation process, thereby realizing the injection of the sample, and performing spectral measurement through the separation component and the conductivity detection component in the internal detection chamber 15, and then transmitting the data to the computer host for analysis through the chromatograph host 1, the functionality is strong and the measurement is accurate.

[0023] Embodiment 2, as Figure 1-4As shown, an ion chromatograph with temperature control can adjust the temperature through the temperature control system inside the chromatograph main unit 1 to ensure the stability of the chromatograph working environment. The temperature sensor 22 inside the chromatograph main unit 1 can detect temperature changes, and instructions can be transmitted to the temperature controller and the cooling fan according to the temperature conditions. When the temperature rises due to long-term operation, the cooling fan 21 starts to achieve air cooling inside the box. If it is in a cold environment for a long time, the temperature controller 19 receives instructions to control the air outlet 20 to heat the detection chamber 15 with hot air. The internal temperature of the device is kept constant by the detection system and air cooling or heating, so that the detection effect of the device is better, and the automatic adjustment reduces the human workload.

[0024] How it works

[0025] It should be noted that the utility model is an ion chromatograph with temperature control. When in use, the raw liquid to be tested is fixed on the fixed plate 24 inside the sample injector 13. The test tube can be supported by connecting the test tube to the mounting groove 25 on the surface of the fixed plate 24. The sample injector 13 transmits the test raw liquid to the quantitative ring 11, and the quantitative ring 11 performs a quantitative process. The second guide tube 9 connected to the outer surface of the quantitative ring 11 can be transported to the chromatograph host 1 to perform a detection process. After the sample injector 13 injects the sample into the chromatograph host 1, the pressure pump 16 provided in the detection chamber 15 can inject the sample into the separation column for a separation process, thereby realizing the sample injection. The separation component and the conductivity detection component in the chromatograph are subjected to spectral measurement, and then the data is transmitted to the computer host for analysis through the chromatograph host 1. The temperature control system inside the chromatograph host 1 can adjust the temperature, and the temperature sensor 22 inside the chromatograph host 1 can detect the temperature change. According to the temperature conditions, instructions can be transmitted to the temperature controller and the cooling fan. When the temperature rises due to long-term operation, the cooling fan 21 starts to realize air cooling inside the box. If it is in a cold environment for a long time, the temperature controller 19 receives the instruction, thereby controlling the air outlet 20 to heat the detection chamber 15 with hot air, and the internal temperature of the device is kept constant by the detection system and air cooling or heating.
