This work describes an update and validation of a method of selective hydride generation (HG) with inductively coupled plasma mass spectrometry for high-throughput screening of toxic inorganic arsenic (iAs) content in seafood samples after microwave-assisted extraction with diluted nitric acid and hydrogen peroxide. High concentration of HCl (8 M) for HG along with hydrogen peroxide in samples leads to a selective conversion of iAs to volatile arsine that is released and transported to the detector, thus allowing for non-chromatographic separation of iAs from the organically bound As species that are considered less toxic or even non-toxic.
