“…185 When coupled with various separation techniques and chemical modiers, optical spectroscopy becomes a valuable tool for identifying As III , As V , DMA, MMA, AsC, AsB, and TAMO, as well as detecting signicant hydride As-sugars and thioarsenate synthesis. 186,187 Nonetheless, the chemical forms and valence states of the analytes inuence the effectiveness of hydride generation (HG). Pentavalent As species undergo HG lesser readily than their trivalent counterpart, therefore detection sensitivity decreased.…”
