Arsenic speciation analysis by hydride generation – cryotrapping – atomic fluorescence spectrometry with flame-in-gas-shield atomizer
Svoboda, Milan ; Musil, Stanislav ; Matoušek, Tomáš ; Rychlovský, P. ; Dědina, Jiří
The main target of this work was further improvement of detection limits in the method of arsenic speciation analysis of tri- and pentavalent human metabolites in complex biological matrices. The method combines selective hydride generation with preconcentration and subsequent separation of substituted arsines in a cryogenic trap.
