Ion exchange (IE)-vapor generation (VG)-inductively coupled plasma (ICP)-mass spectrometry (MS) method has been employed to simultaneously determine trace amounts of As, Se, and Hg in acidic conditions. Before hydride generation, anion-exchange column was used to separate the analytes from the matrix. Effects of sample solution acidity, eluant conditions and concentrating time were investigated and...
A newly developed hydride generation-inductively coupled plasma-mass spectrometry (HG-ICP-MS) system was employed to determine trace amounts of lead in geological and biological samples. Laboratory-made single-stage and double-stage gas-liquid separators (GLSs) were investigated in order to replace the consumable membrane-GLS. Possible reasons were given why double-stage GLSs were superior over the...
