Description

Technical Field

[0001] The utility model relates to the technical field of ion chromatographs, in particular to a novel self-cleaning ion chromatograph. Background Art

[0002] A chromatograph is a device used for chromatographic separation and analysis, comprising a sampling system, detection system, recording and data processing system, temperature control system, and mobile phase control system. Chromatographs are widely used to analyze the content of chemical products and polymer materials. Ion chromatographs, a type of high-performance liquid chromatograph, are primarily used for analyzing environmental samples, including anions and cations in surface water, drinking water, rainwater, and domestic sewage. They also have extensive applications in the food, health, petrochemical, water, and geology industries.

[0003] When using an ion chromatograph to analyze samples, since the chromatograph components are precision devices with poor resistance to interference from particulate impurities, the samples to be tested need to be filtered before processing.

[0004] However, the existing treatment method generally adds a filtration process to the front-end process of the chromatograph, which requires manual and relatively tedious filtration operations. At the same time, the filtration equipment does not have a self-cleaning function. As the use time increases, the filtration performance of the filtration equipment gradually decreases, and the filtration equipment needs to be maintained regularly, which requires a large maintenance workload. Therefore, it does not meet the existing needs. In this regard, we propose a new self-cleaning ion chromatograph. Utility Model Content
