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


Hexavalent chromium, also referred to as chromate or Cr(VI), is considered toxic and potentially carcinogenic, which is why its concentrations in drinking water should be kept as low as possible. Determination of Cr(VI) is performed by combining ion chromatography with ICP/MS. Separation takes place on the Metrosep A Supp 1 Guard/4.6.
