Reduction of transport loses of volatile form of cadmium for determination by EcHG - in situ trapping - ETAAS
 Nováková, Eliška ; Rychlovský, Petr (advisor) ; Červený, Václav (referee)
This thesis deals with possible ways of improving sensitivity and repeatability of determination of cadmium by EcHG - ETAAS. The main complication of this coupled method is condensation of water vapors in the transport capillary, which takes part in the losses of the volatile form of cadmium. Possible solution or at least restriction of the above mentioned problem is heating of the transport route. Experiments also show that reducing the ratio area/volume of transport capillary doesn't lead to reduction of loses of the volatile form of cadmium.

Chemické generování těkavých sloučenin stříbra pro potřeby AAS: studie účinnosti transportu pomocí radioizotopu .sup.111./sup.Ag a in-situ kolekce na křemenném povrchu
 Musil, Stanislav ; Kratzer, Jan ; Vobecký, Miloslav ; Matoušek, Tomáš
The method of chemical vapour generation of silver by means of sodium tetrahydroborate was futher developed in order to minimize transport losses. The possibility of collection of volatile silver species directly in the atomizer is presented.
