1、 Product Introduction
Ion chromatography is a type of high-performance liquid chromatography, also known as high-performance ion chromatography (HPIC) or modern ion chromatography. Ion chromatography is mainly used for the analysis of environmental samples, including anions and cations in surface water, drinking water, rainwater, domestic and industrial wastewater, acid precipitates, and atmospheric particulate matter, as well as trace impurities in water and reagents related to the microelectronics industry. Therefore, it is widely used in fields such as tap water, environmental monitoring, hygiene and epidemic prevention, quality inspection, petrochemicals, geological exploration, and pharmaceutical production inspection.
