On-line preconcentration for capillary electrophoresis-atomic fluorescence spectrometric determination of arsenic compounds.

Abstract

An on-line preconcentration method was developed for capillary electrophoresis (CE) with hydride generation-atomic fluorescence spectrometric (HG-AFS) detection of arsenite, arsenate, dimethylarsenic acid, and monomethylarsenic acid. These arsenic species were negatively charged in the sample solution with high pH. When the potential was applied to the… (More)
