CHROMATOGRAPHIC DETERMINATION OF PHENYLARSENIC COMPOUNDS

Gas chromatographic (GC) and liquid chromatographic methods for the in vestigation of phenylarsenic compounds are presented. With gas chromat ography using an electron capture detector (ECD), the chemical warfare agents PFIFFIKUS, CLARK I and CLARK II can be detected. After derivat ization with mercaptans and dimercaptans the sum of diphenylarsenic co mpounds resp. phenylarsenic and phenylarsonic compounds can be detecte d as the mercapto reap. dimercapto derivatives. High performance liqui d chromatography (HPLC) analysis may be used for the detection of trip henylarsenic compounds and ADAMSITE.
