Determination of chromate in water applying IC-ICP/MS detection

contributed by Metrohm | 11/14/2016

Hexavalent chromium (chromate) is considered toxic and potentially carcinogenic for which reason its concentration in environmental and drinking water should be as low as possible. The determination of Cr(VI) can be ideally done by ion chromatography coupled to ICP/MS. The separation is performed on a Metrosep A Supp 1 Guard/4.6 column. The chromatogram stems from a chromium-spiked (1 μg/L) wastewater sample.
