Atomization of arsane in a 17 W planar quartz dielectric barrier discharge (DBD) atomizer was optimized and its performance compared to that of a multiple microflame quartz tube atomizer (MMQTA) for AAS. Atomization efficiency in DBD was estimated to be 100 % of that reached in the MMQTA. A novel approach to in-situ preconcentration of arsenic in a DBD atomizer, simple and fast, with 100 % efficiency, was developed and validated.
