Název v původním jazyce

Laser-induced fluorescence measurements of atomic lead in hydride atomizers for atomic absorption and atomic fluorescence spectrometry

Popis výsledku v původním jazyce

We developed a theoretical model of the laser-induced fluorescence process, which predicted the shape of fluorescence non-linear dependence on energy of laser pulses. Thanks to that model, we are able to evaluate the LIF measurements also in highly saturated regime. We used this aproach for measurement of concentration of atomic lead produced in hydride atomizers for atomic absorption spectrometry, in order to understand the atomization process. We found out that the lead atoms occur mainly in the centre of the flame atomizers and the key role in atomization process is played by hydrogen atoms.
