Analysis of arsenic species is made challenging due to diverse sample matrices. To circumvent these problems, an HPLC ICP-MS method has been developed. Resolution of arsenic compounds is achieved by ion exchange chromatography on a Hamilton PRP-X100 column, a 55% cross-linked polystyrene-divinylbenzene copolymer functionalized with quaternary ammonium anion-exchanger group.
