Six arsenic species, arsenite, arsenate, monomethylarsonic acid, dimet
hylarsinic acid, arsenobetaine and arsenocholine, were separated by co
upled column ion chromatography using carbonate and nitric acid as elu
ents, and were detected by inductively coupled plasma mass spectrometr
y. Coupling of an anion column with a cation column made the simultane
ous determination of both the cationic and the anionic arsenic species
possible by ion chromatography. Extremely low detection limits, below
0.2 mu g/l (as arsenic), were obtained for all the species studied.
