Several design types of hydride atomizers were characterized in terms of plasma temperature, absolute concentration and spatial distribution of H radicals as important species responsible for hydride atomization determined by two photon laser induced fluorescence (TALIF). For selected elements, the absolute concentration of free analyte atoms and their spatial distribution was measured by LIF allowing to quantify atomization efficiency.
