Autor: Věra Pacáková, Jiří Barek, Pham Tuan Hai, Ivana Švagrová, Karel Štulík, Jiří Zima

Publikováno v: Fresenius' Journal of Analytical Chemistry. 350:678-683

Optimised conditions have been found for the separation of N-nitroso-N-methylaniline derivatives substituted in the position 4 (4-R-NMA, where R =- H,- CH3, - OCH3, - Cl, - CN, - OH and - NO2), using reversed phase HPLC with a C18 chemically bonded s

Autor: Jiří Zima, Viktor Mejstřík, Ivana Švagrová, Jiří Barek

Publikováno v: Collection of Czechoslovak Chemical Communications. 56:2815-2826

Optimum conditions were found for the determination of N-nitroso-N-methyl aniline and its derivatives substituted in the 4 position by -CH3, -OCH3, -Cl, -CN, -OH or -NO2 groups by fast scan differential pulse voltammetry at a hanging mercury drop ele

Determination of narciclasine in serum by reversed-phase high-performance liquid chromatography: comparison of amperometric, ultraviolet photometric and fluorescence detection

Autor: Karel Štulík, Věra Pacáková, Francesco M. Veronese, Paolo Caliceti, Ivana Švagrová

Narciclasine was determined in the blood of mice by reversed-phase high-performance liquid chromatography, using a C18 stationary phase and a mobile phase of methanol—0.025 M potassium dihydrogen phosphate (50:50, v/v) of pH 5.5. Amperometric detec

POLAROGRAPHIC AND VOLTAMMETRIC DETERMINATION OF N,N'-DINITROSOPIPERAZINE

Autor: Jiří Zima, Jiří Barek, Ivana Švagrová

Publikováno v: ResearcherID

Polarographic reduction of the genotoxic N,N’-dinitrosopiperazine was studied and its mechanism was suggested. Optimum conditions were established for the determination of this substance by tast polarography over the concentration region of 1 . 10-

THE POLAROGRAPHIC AND VOLTAMMETRIC DETERMINATION OF 5-(3-PHENOXYSULPHENYLAZO)-6-HYDROXY-3-CYANO-1,4-DIMETHYL-2-PYRIDONE

Autor: Ivana Švagrová-Hauserová, Jiří Zima, Jiří Barek

Publikováno v: ResearcherID

The polarographic reduction of the title azodye has been studied, a mechanism was proposed and optimal conditions were found for the determination of this substance by TAST polarography in the range 5.10-5-2.10-6 mol l-1 and differential pulse polaro
