Ion Chromatography

What is Ion Chromatography?

Ion chromatography is a kind of high-performance liquid chromatography, so it is also called high-performance ion chromatography (HPIC) or modern ion chromatography. It is a liquid chromatography method for analyzing anions and cations. 

Applications: IC is mainly used for the analysis of environmental samples, including anions and cations in samples such as surface water, drinking water, rainwater, domestic sewage and industrial wastewater, acid deposits, and atmospheric particles. In addition, it has a wide range of applications in the fields of food, sanitation, petrochemicals, water, and geology.
