Chromatogram for a microwave extract generated from a soil sample double-spiked with 50Cr(III) and 53Cr(VI).
Chromium is encountered primarily in two forms: Cr(III) and Cr(VI). Whereas Cr(III) compounds pose no major risk (and are essential for humans), hexavalent chromium (also called hexachrome, chrome-6, and Cr(VI)) is harmful. The strong oxidizing agent Cr(VI) is classified as carcinogenic, mutagenic, and damaging to the DNA. Acute chromium(VI) poisoning leads to renal damage.
This application provided by Metrohm shows the determination of hexavalent and soluble trivalent chromium (Cr+6 and Cr+3) species in soil, solid samples and pharmaceuticals using ion chromatography–inductively coupled plasma mass spectrometry (IC-ICP-MS) with speciated isotope dilution methodology (USEPA, SW846 method 6800 – SIDMS).
