Coupling of an ion chromatograph used for anion chromatography with an inductively coupled argon plasma mass spectrometer is used for the simultaneous determination of common anions and anions of heavy elements without any matrix separation techniques. Up to 0.1% sodium chloride does not interfere significantly with arsenic determination.
In addition to its use for matrix separation, the method can be used as an element speciation technique, which is shown by the analysis of urine to determine arsenic.
