Columns were connected "on line" to a hydride generation atomic fluorescence spectrometer (HG-AFS) using a UV lamp between the separation and detection system. The repeatability of the results obtained by the developed method was under 15% (R.S.D.) for all Se species; the detection limit ...

This is also a problem when different arsenic species (organic arsenic species such as arsanilic acid, nitarsone and roxarsone) are to be determined in animal meat by HPLC-UV-HG-AFS, which is the basis of this work. In order to improve the detection power, methods of signal treatment ...
SPECIATION OF FIVE SELENIUM COMPOUNDS BY HPLC-HEATING-UV-HG-AFS1. Protease XIV from Streptomyces griseus (4,4 units/mg)2. Subtilisin A, type VIII, from Bacillus licheniformis (8 units/mg)3. Protease from Bacillus licheniformis (13,1 units/mg)4. Without enzymeVitoulová, Ing Eva...
The conditions of IP-RP-HPLC-UV-HG -AFS were studied. The conditions of the pretreatment sample, such as types and dosage of proteinases, were investigated. The detection limits (LODs) for six Se species were between 0.77 and 1.77 μg·L1. Then, the proposed method has been successfully ...
Arsenic speciation analysis in dried seaweeds was carried out using an on-line HPLC-UV-thermo-oxidation-HG-AFS system. Species separated and quantified were: arsenite [As(III)], arsenate [As(V)], monomethylarsonic acid (MMA), dimethylarsinic acid (DMA) and different arsenosugars. Extraction ...
