- 中文摘要: Utilization 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 2ppt (ng/L) and 33ppt 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.
