Technical Field

The utility model relates to an environment detection area especially relates to an ion chromatograph with critical interface autoalarm of leacheate.

Background

The separation mechanism of the ion chromatograph is mainly ion exchange, and there are 3 separation modes, which are ion exchange chromatography, ion exclusion chromatography and ion pair chromatography. Detectors for ion chromatographs fall into two broad categories, namely electrochemical detectors and optical detectors. The electrochemical detector comprises conductance, direct current ampere, pulse ampere and integral ampere; photochemical detectors include ultraviolet visible and fluorescent light. The eluent storage tank is a device for storing the eluent in an eluent conveying system of the ion chromatograph, and in the using process of the ion chromatograph, the eluent is required to be firstly used for washing until the instrument stably operates, and then a sample is taken into a chromatographic column from the eluent to be subjected to next separation and analysis.

However, if the measured sample amount is too large, the leacheate in the leacheate storage tank is easily consumed quickly, and when the leacheate is consumed until the filter head is separated from the liquid, external air enters the instrument along the guide pipe to form bubbles, so that the accuracy of the test result is influenced.

In the existing market, the problems are solved by two methods. The first method is to store a large amount of the leacheate by increasing the volume of the leacheate storage tank, but this method easily causes the waste of the leacheate; the second method is manual monitoring by squatting, and once the leacheate is consumed until the filter head is separated from the liquid, the leacheate is added and supplemented by workers in time, but the method wastes human resources.
