Utilisation of a miniature anion‐exchanger preconcentration column of Dowex 1‐X8 to increase the sensitivity for As and Se determinations by inductively‐coupled‐plasma mass spectrometry (ICP‐MS) is described. The ion signal was enhanced were 15 fold for As and 20 fold for Se. The multielement detection limits were 2 ppt (ng/L) and 33 ppt for As and Se, respectively. This flow injection ICP‐MS method was applied to the determination of trace levels of arsenic and selenium in riverine reference material SLRS‐2 and spring water samples.
