Feasibility of quantitative inorganic arsenic speciation at the parts-per-trillion level using solid phase extraction and femtosecond laser ablation inductively coupled plasma mass spectrometry
Abstract:Toxicity of arsenic compounds depends on the chemical structure as well as the concentration. Thus, separation of the toxic arsenic species should precede the quantification for the accurate toxicity assessment. Ion chromatography inductively coupled plasma mass spectrometry (IC-ICP-MS) has been the most popular method for separation and quantification of toxic arsenic species. However, the method requires complex instrument, elaborate sample preparation, and long analysis time. In this work, toxic inorganic a… Show more
“…The use of lasers to study As speciation has increased this year. Quantitative iAs speciation at the ng kg −1 level using SPE and femtosecond LA-ICP-MS has been reported by Lee et al 33 The iAs species in water samples were separated by SPE using a SAX membrane filter prior to LA. The pH value of the sample was adjusted to pH 4 with ammonium hydroxide and phosphoric acid to facilitate the complete separation of iAs from the organic As species.…”
