Chromium Speciation in Drinking Water by LC-ICP-MS

Chromium speciation in drinking water by LC-ICP-MS


Knowing the concentration of hexavalent chromium in environmental systems and samples which will be consumed is more important than knowing the total chromium concentration. This is especially true for drinking water. This work describes the use of LC-ICP-MS to measure both trivalent and hexavalent chromium in drinking waters, with the goal of presenting a suitable methodology for analyzing the range of concentrations encompassed by the new legislation.
