Ion Chromatography (IC) Ion chromatography is used for the analysis of aqueous solutions. These devices are able to measure the concentrations of major anions in the solutions such as fluoride, chloride and nitrate to name a few, in the parts per billion (ppb) range. Ion chromatography is a form of liquid chromatography that measures concentrations of ionic species by separating them based on their interaction with a resin (Bruckner, 2009). The ionic species separate differently depending on their type and size. Sample solutions pass through a pressurized chromatographic column where the ions are absorbed by the column components. An ion extraction liquid, known as the eluent, runs through the column separating the absorbed ions. The elution time, or time it takes for the ion to move though the column, of each type of ion determines the ionic concentrations in the sample. Typical applications of ion chromatography include drinking water analysis for pollution and other constituents, determination of water chemistries in aquatic ecosystems,
