Ion chromatography

Ion chromatography utilizes ion-exchange resins to separate aqueous ions based on their interaction with a given resin. Ions are detected by electric conductivity. The method is used for the analysis of dissolved anions, such as F-, Cl-, NO2-, NO3-, Br-, SO42- and PO43-, dissolved cations like Li+, Na+, NH4+, K+, Mg2+ and Ca2+, as well as organic components, such as acetate and oxalate in aqueous solutions.
