The use of dielectric barrier discharge (DBD) plasmas for gas phase dissociation of analyte molecules, after vapor generation and prior to spectrometric detection, is discussed. Their performance in terms of sensitivity, detection limit, resistance to interferences, etc. is evaluated and compared to atomizers/excitation sources routinely used in atomic absorption, fluorescence or emission spectrometry. Not only the applicability of DBDs to element determination at trace and ultratrace levels is assessed, but also their potential for analyte preconcentration and speciation analysis is evaluated. An assessment of atomization efficiency and insights into the fate of analyte free atoms in the DBD plasmas are provided.
