Flow-injection hydride generation and in situ concentration of Se and Te hydrides in graphite furnace atomic absorption spectrometry (AAS) can be automated using a highly stable trapping reagent replacing the Pd modifier. In a systematic study, carbide-forming elements (Zr, Nb, Ta, W) and noble meta
