AN43098: Speciation analysis of Cr (III) and Cr (VI) in drinking waters using anion exchange chromatography coupled to ICP-MS
DescriptionSpeciation determinations of ionic compounds are important to determine the concentration of the more toxic form in the total elemental composition. Chromium is an industrial waste contaminant that can have serious health effects and therefore requires monitoring in municipal water systems. This method determines Chromium VI and Chromium III species in a municipal drinking water sample. The ions are separated by ion chromatography (IC) on an IonPac AG7 guard column and detected by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) at ng/g. This method is further optimized in AN43175.
