Annotation	Atomization of Pb, Bi, Se, Te and Ge hydrides in QTA and DBD based atomizers for AAS is discussed. Sensitivity and resistance to interferences under optimum conditions is evaluated. Mechanism of atomization was investigated by laser induced fluorescence (LIF). As species were separated by HPLC to be subsequently treated by post-column VSG followed by in-situ preconcentration in DBD and AAS detection. Preconcentration efficiency exceeds 90% for all four As species tested while the system is fully automated. Analytical figures of merit and method validation by certified reference material of urine is presented.
