Study of selenium distribution in graphite tube after in situ collection 75SeH2 by "Image plate" autoradiography
Korunová, Vlasta ; Selecká, Anna
The aim of the work was the determination of surface area of the trapped analyte inside the graphite tube, by "Image plate" autoradiography method with use of selenium-75 isotope as radioindicator.
New developments in hydride atomizers for atomic absorption and atomic fluorescence spectrometry
Dědina, Jiří ; Korunová, Vlasta ; D'Ulivo, A.
The most recent developments of multiatomizers and FIFS were described and performance of the atomizers namely in terms of resistance to atomization interferences and of minimization of the limit detection for AAS and AFS was discussed.
Evaluation of distribution of toxicologically important elements in urban dust from two Prague tunnels subway and road by sequential leaching and methods ICP-AES and GF AAS
Sysalová, Jiřina ; Száková, J. ; Drábek, M.
The three-stage sequential extraction procedure for speciation of potentially toxic trace elements As, Cd, Cr, Mn, Ni, Pb and Zn has been applied to establish their distribution in urban dust from two Prague tunnels road Letná with automobile traffic and subway, station Muzeum. Analytes were determined by ICP-AES and GF AAS method.
In situ trapping of hydride forming elements within miniature atomizers New observations
Dočekal, Bohumil
New miniature atomization/collection devices were designed for in situ trapping of hydride forming elements. The performance of those based on graphite, bare and modified, and on other refractory materials (W, Mo) was investigated with respect to the efficiency of trapping procedure, influence of experimental parameters, geometry and surface modification, and to atomizer life time, gas composition.
