Abstract

A technique to determine four species of arsenic (AsIII, AsV, dimethylarsinic (DMAs), and monomethylarsonic (MMAs) acids) where high-performance liquid chromatography was coupled to an atomic fluorescence spectrometer using an ultrasonic nebulizer as an interface has been further improved by the use of hydride generation. The effect of hydride conditions on signal intensities has been investigated. The detection limits for AsIII, AsV, DMAs, and MMAs were 2.5, 6, 3.2, and 2 ng, respectively (at 250 mm3 volume injected). The linearity for all four arsenic species were in the range 25-1000 ng.
