The use of slurry sampling flow injection vapor generation
ICP-MS provides a simple, rapid and accurate procedure to determine
As, Hg and Pb in herbs without complicated sample pretreatment.
The detection limits, obtained for As, Hg and Pb with this
system, are low enough for the determination of As, Hg and Pb in
many real samples. The analysis results agreed with the reference
values. Precision between sample replicates was better than 7% for
all the determinations. The procedure can be used as an alternative
to the existing procedures for the analysis of herbs.
