Low-Level Speciated Analysis of Cr(III) and Cr(VI) Using LC(IC)-ICP-MS
17 Sep 2014

Occupational exposure to Cr(VI) is strictly controlled in many industries; recent studies have also indicated a health risk from chronic exposure to low levels of Cr(VI) by ingestion. As a result, there is a need for a routine, highly sensitive method to determine both Cr(III) and Cr(VI) in a wide range of sample types. This application note describes a HPLC-ICP-MS method using collision/reaction cell ICP-MS operated in helium cell mode.
