Popis: A combined ion chromatography (IC) with inductively coupled plasma mass spectrometry (ICP-MS) system as an element-selective detector has been used for the determination of arsenic compounds. Seven arsenic compounds were separated by cation-exchange chromatography. Subsequently, the separated arsenic compounds were directly introduced into the ICP-MS and were detected at m/z=75. Detection limits for the seven arsenic compounds ranged from 0.8 to 3.8 μg AS/l. The IC-ICP-MS system was applied to the determination of arsenic compounds in the urine of dimethylarsinic acid (DMAA)-exposed rats. DMAA was the most abundant arsenic compound detected. Arsenous acid, monomethylarsonic acid and trimethylarsine oxide were also detected.
