Abstract
Abstract An elegant method for the determination of monomethylarsonic acid and dimethylarsinic acid in biological materials is described. The methylarsenic acids are derivatized with thioglycolic acid methylester to yield lipophilic species, which can be determined by gas chromatography using a flame ionization detector or the more selective thermionic specific detector. The method permits the quick determination of methylarsenic acids in concentrations as low as 10 ng ml -1 in urine or blood.
