Impact/Purpose:

To establish a Standard Operating Procedure (SOP) for the analysis of arsenic in estuarine type coastal waters by Gaseous Hydride ICP-MS.

Description:

The determination of arsenic in estuarine waters usually involves a matrix removal and/or pre-concentration prior to analysis because of the high salt content in these waters. The salinity also produces analytical challenges in terms of interferences and instrument stability. A hydride generation SOP should provide the capability for part per trillion detection limits required for arsenic monitoring in estuarine waters.
