Thermospray (TSP) sample introduction methods have been found to selectively deposit Cr(III) in the presence of Cr(VI) and thus provide a direct, nonchromatographic speciation capability for these chromium oxidation states. Previous results have shown that the sensitivity for Cr(III) could be reduce
