New electrochemical cell for studies of phthalocyanines
Hudská, V. ; Janda, Pavel ; Nesměrák, K.
We have developed a new type of electrochemical cell for electrochemical studies of phthalocyanines. The cell employs a HOPG as a working electrode covered by a thin layer of dichlorobenzene with dissolved phthalocyanine. The layer of dichlorobenzene solution is overlaid by aqueous supporting electrolyte solution where the reference and counter microelectrodes are immersed.
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.
Kryogenní záchyt arsenu pro speciační analýzu arsenu technikou hydridového generování s detekcí atomovou absorpční spektrometrií
Svoboda, Milan ; Kratzer, Jan ; Vobecký, Miloslav ; Rychlovský, P. ; Dědina, Jiří
The general aim of this work was to contribute to further improvement of the method for complete speciation analysis of trivalent and pentavalent human metabolites of arsenic in complex biological matrices. The main target of this work was to investigate processes during the cryotrapping procedure and find optimum conditions.
