Ion Chromatography
Ion chromatography (IC) is a special technique of ion exchange chromatography that is used to analyse inorganic ions and organic acids in particular. The capacity of the ion exchange resin is many times lower compared to ion exchange chromatography. Typical applications are, for example, the analysis of anions or cations in drinking water or the analysis of organic acids in beverages.
