Martina Riesová Abstract of Ph.D. Thesis Capillary electrophoresis is a method of choice in many analytical laboratories for its high separation efficiency, rapidity, low consumption of chemicals and therefore low costs. Inherent to each electrophoretic separation system are system peaks, which can significantly affect or confuse the electrophoretic results. In capillary zone electrophoresis, position of system zones can be predicted easily and reliably by means of prediction software based on a theoretical description of electromigration. However, the prediction of only position of a system zone may not be sufficient for identification of system peaks in obtained electropherograms. Therefore, an existing theoretical model was significantly extended and new version of PeakMaster software (PeakMaster 5.3) was introduced in the framework of this thesis. PeakMaster 5.3 enables to predict not only the positions of system zones, but also their shapes and polarity. Thus, PeakMaster 5.3 improves the prediction possibility of overlapping or interaction of system peaks with analyte peaks. Moreover, composition of the sample can be optimized in order to obtain convenient shapes and amplitudes of system peaks. The applicability of capillary zone electrophoresis can be extended by addition of a complexation agent into...
