Description	The essential goal of the project is to enhance performance of the atomic absorption and fluorescence detectors for speciation analysis by using advanced new-generation atomizers devised in our laboratory. A particular emphasis will be put on miniaturization of atomizers as well as all parts of the experimental setup serving to generate, separate or trap hydrides and also on redesigning atomic fluorescence spectrometer. The potential of electrochemical hydride generation and in-atomizer trapping to enhance the detection power will be examined as well. Arsine, selenium hydride and stibine will be used as the model analytes. The corresponding radiotracers will be applied to check the efficiency of hydride generation and to track ways of analyte transfer within individual tested designs of the whole experimental set-up. The most promising achievements reached will be tested for As speciation analysis in biological matrices. (en) Hlavním cílem projektu je využití hydridových atomizátorů nové generace vyvinutých v naší laboratoři pro zlepšení funkce atomového absorpčního a fluorescenčního detektoru pro speciační analýzu. Zvláštní pozornost bude věnována miniaturizaci atomizátorů i všech částí aparatury sloužících pro generování, separaci či kolekci hydridů a také optimalizaci optické i elektronické trasy atomového fluorescenčního spektrometru. Rovněž bude ověřen potenciál elektrochemického generování hydridů a kolekce hydridů v atomizátoru. Arsan, selenovodík a stiban budou sloužit jako modelové analyty. Příslušné radiotracery budou využity pro stanovení účinnosti generování a pro sledování transferu analytů v jednotlivých testovaných variantách experimentálních zařízení. Nejslibnější varianty aparatur a procedur budou použity pro speciační analýzu As forem v biologických matricích.
