Performance of this device based on electrothermal vaporizer equipped with raw and modified graphite materials is reported. Optimization of trapping efficiency of analytes (As, Se) with respect to collection temperature, geometry and sort of graphite material and its modification by noble metals, to analytical figures of merit and to analytical lifetime of the vaporizer, to influence of carrier and stripping gases, to composition and related gas flow rates is discussed.
