	Determination of Inorganic Arsenic in Samples of Marine Origin Marschner, Karel ; Matoušek, Tomáš ; Dědina, Jiří ; Musil, Stanislav A fast screening method for determination of inorganic arsenic in marine samples was developed. This method is based on selective\nhydride generationanddetectionby inductively coupled plasmamass spectrometry. Using a high concentration of hydrochloric acid\ntogether with hydrogen peroxide for hydride generation leads to selective conversion of inorganic arsenic species into arsane. The\naccuracy of this method was verified by comparative analyse by high performance liquid chromatography coupled with hydride generationandatomic\nfluorescence detection. Detailed record
	Arsenic speciation by hydride generation coupled with atomic fluorescence spectrometry Marschner, Karel ; Musil, Stanislav ; Rychlovský, P. ; Dědina, Jiří Post-column hydride generation for arsenic speciation was used and the demethylation of Arsenic species during hydride generation was investigated. Detailed record
	Arsenic speciation analysis by hydride generation – cryotrapping – atomic fluorescence spectrometry with flame-in-gas-shield atomizer Svoboda, Milan ; Musil, Stanislav ; Matoušek, Tomáš ; Rychlovský, P. ; Dědina, Jiří The main target of this work was further improvement of detection limits in the method of arsenic speciation analysis of tri- and pentavalent human metabolites in complex biological matrices. The method combines selective hydride generation with preconcentration and subsequent separation of substituted arsines in a cryogenic trap. Detailed record
	Arsenic speciation analysis by cryogenic trapping – hydride generation – atomic absorption spectrometry; Investigation of water vapour dryers Svoboda, Milan ; Taurková, Petra ; Matoušek, Tomáš ; 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. Detailed record
	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. Detailed record
