Abstract

A GC-MS method has been developed to determine two methylated arsenic species in human urine samples. This GC-MS method was compared with high-performance liquid chromatography-hydride generation-atomic fluorescence spectrometry. The yield of derivatisation for dimethylarsinic acid (DMA) and monomethylarsonic acid (MMA) using thioglycol methylate was measured. The detection limits for DMA and MMA using this GC-MS method are 0.95 and 0.8 ng/cm3, respectively.
