Contributions to Volatile Compound Generation of Arsenic, Silver and
Musil, Stanislav
(EN) The presented dissertation thesis summarizes the results contained in five original research papers that were published in prestigious international scientific journals in the field of analytical chemistry and atomic spectrometry. It is devoted to the method of generation of volatile compounds using a tetrahydroborate reaction and detection in a quartz multiatomizer by atomic absorption spectrometry. The thesis can be divided into two thematic parts - speciation analysis of arsenic based on hydride generation technique with collection and separation in a cryogenic trap and generation of volatile species of transition metals. In the first thematic part pre-reduction of pentavalent inorganic and methylated arsenicals has been studied. A simple setup for on-line pre-reduction employing thioglycolic acid as a fast pre-reductant has been developed, connected with a current hydride generator and applied/verified to oxidation state specific arsenic speciation analysis of human urine samples. In the same method the possibility of drying the gaseous phase from water vapor has been investigated to avoid incidental blocking the cryogenic trap by frozen water and to decrease fluctuations of signal baseline. Pronounced losses of methylated species have been discovered on Nafion tube dryer currently used in...

Former Monastery of Order of Minims nearby Nová Bystřice
MUSIL, Stanislav
This thesis deals with the establishment of the Paulans order, and his activities at Czech, establishment of the Paulans monastery of the Holy Trinity by Nová Bystřice. It describes the important circumstances of the paulans monkery arrival to this convent. Thesis also observe the termination of the convent in 1533 and his new establishment in 1626 and following 200 years of this greatest properity. Then it also describes the final termination of the convent in 1785, caused by the reforms of emperor Josef II.

Gold chemical vapor generation by tetrahydroborate reduction for AAS: Radiotracer efficiency study and characterization of gold species
Musil, Stanislav ; Arslan, Y. ; Kratzer, Jan ; Vobecký, Miloslav ; Benada, Oldřich ; Matoušek, Tomáš ; Rychlovský, P. ; Ataman, O. Y. ; Dědina, Jiří
The main objective was to assess the generation efficiency in the optimized method of chemical vapor generation of gold by means of 198,199Au radioindicator. We also intended to characterize the volatile Au species formed by tetrahydroborate reduction.
