Ion chromatography

Ion chromatography is a kind of liquid chromatography which uses ion-exchange resins to separate aqueous ions based on their interaction with the resin. Ions are detected by electric conductivity.

The method is used for analysis of inorganic anions such as fluoride, chloride, nitrite, bromide, nitrate, sulfate and phosphate, inorganic cations like lithium, sodium, ammonium, potassium, magnesium and calcium as well as organic ions such as acetate and oxalate in aqueous solutions.
