New Report published on Quantitative Chromium Species Measurement by Nick Boley

A new report has been published under the Government Chemist’s Advisory Function which demonstrates a method for the quantitative determination of chromium species in clean and effluent waters.

Chromium (VI) is a significantly more toxic species than other chromium species (particularly the more common Chromium (III)) and difficulties in determining it accurately in environmental matrices has long been problematical. The method involved was ion pair/chelation reversed phase HPLC-ICPMS, and represents an excellent piece of work which demonstrates this technique and opens doors for the measurement of other species and chromium species in other matrices.

The work was carried out by John Entwisle and Heidi Goenaga-Infante in LGC Science & Technology’s Specialist Inorganic Analysis Team. The report is can be found on the Government Chemist website.
