Description
For quantification of organic (e.g. acetate, formate) and inorganic anions (e.g. chloride, sulfate) in aqueous samples ion exchange chromatography is used.
The quantification of the dissolved organic carbon (DOC) in aqueous samples and chromatographic separation of the DOC into different fractions and quantification of these fractions in aqueous samples is done via liquid chromatography – organic carbon detection (LC-OCD).
