Sample preparation and their measurement by EDS methods
Kostelník, Tomáš ; Jaššo, Kamil (referee) ; Čudek, Pavel (advisor)
This bachelor´s thesis is focused on preparation and analysis of samples by energy dispersive spectroscopy using scanning electron microscopy. In the theoretical the main differences between environmental scanning electron microscopy and scanning electron microscopy are described. There is also a description of basic knowledge regarding energy dispersive spectroscopy. The generation and detection of signals arising from the interaction of a beam of primary electrons with a sample is also explained, with emphasis on the description, generation and distribution of these signals. The experimental part is focused on sample preparation and analysis.

Influence of working conditions on the results of EDS in ESEM
Pospíchal, David ; Čech, Ondřej (referee) ; Čudek, Pavel (advisor)
The bachelor thesis deals with energy dispersion spectroscopy and detection of characteristic X-rays in the field of environmental scanning electron microscope. The aim of the semester work is to compare the results of elemental microanalysis of samples under optimal conditions and to monitor changes of results, when changing working conditions, resp. nitrogen and water vapor pressure in the sample chamber of the scanning electron microscope Vega3 XMU with LaB6 cathode. TESCAN, a.s equipped with Xflash 6 | 10 spectrophotometer. Bruker
