Radical theory of hydride atomization confirmed after four decades - determination of H radicals in the quartz hydride atomizer by two-photon absorption laser-induced fluorescence
Original language description
To reach an excellent performance for elemental and speciation analysis offered by the hydride generation coupled to atomic absorption/fluorescence detectors, an optimization of hydride atomization is required. It can be realized in a straightforward way based on a knowledge how experimental conditions influence the distribution of hydrogen atoms in a given atomizer type. In the quartzQuartz-tube atomizersperformance tube atomizer, most often employed hydride atomizer for atomic absorption spectrometry, two-photon absorption laser-induced fluorescence (TALIF) was employed (i) to bring after four decades for the first time a conclusive proof of the existence of H radical population sufficient to atomize hydrides thus confirming unambiguously the radical theory of hydride atomization and (ii) to determine distribution of H radicals in the atomizer. The superb power of TALIF to determine spatial distribution of H radicals in hydride atomizers opens a way to an elegant optimization of hydride atomization.
