Preconcentration of selenium hydride in a planar dielectric barrier discharge (DBD) atomizer was optimized with detection by atomic absorption spectrometry. The use of 75Se radiotracer combined with radiometry and autoradiography allowed proving efficient analyte trapping (90%) in a small spot in the central part of the DBD optical arm whereas incomplete analyte release was found responsible for preconcentration efficiency of 70%.
