Simultaneous speciation and determination of arsenic, chromium and cadmium in water samples by high performance liquid chromatography with inductively coupled plasma mass spectrometry

The simultaneous separation and determination of As(iii), As(v), monomethylarsenic acid (MMA), dimethylarsenic acid (DMA), Cr(iii), Cr(vi) and Cd(ii) in water samples have been carried out by anion exchange liquid chromatography with inductively coupled plasma mass spectrometry.
