We have also been exploring dielectric barrier discharges (DBD) for atomization of hydrides for AAS and AFS. Performance of individual designs of DBD atomizers for both atomic spectrometry detectors will be compared - also with conventional quartz tube atomizers. Most notably, the promising prospect of in-atomizer preconcentration of volatile species forming elements in DBD atomizers will be assessed. In addition, advantages and disadvantages of in-atomizer preconcentration of Ag and Au in sapphire and quartz traps coupled to AAS will be presented.
