Matrix effects in LC-MS analysis: occurrence, evaluation, and their elimination
Svoboda, Pavel ; Nováková, Lucie (advisor) ; Švec, František (referee) ; Havliš, Jan (referee)
Abstract Charles University, Faculty of Pharmacy in Hradec Králové Department of Analytical Chemistry Candidate: Mgr. Pavel Svoboda Supervisor: Assoc. Prof. PharmDr. Lucie Nováková, Ph.D. Advisor: RNDr. Hana Vlčková, Ph.D. Title of Doctoral Thesis: Matrix effects in LC-MS analysis: occurrence, evaluation, and their elimination The dissertation thesis deals with the issue of matrix effects in analysis using liquid chromatography coupled to mass spectrometry (LC-MS). LC-MS represents a well-established, widely used, and powerful tool in the field of qualitative and quantitative analysis of a wide range of different compounds. Despite all the advantages offered by LC-MS such as sensitivity, selectivity, and robustness, it suffers from a major drawback represented by matrix effects. This undesirable phenomenon affects important parameters of LC-MS method such as accuracy, precision, linearity, limit of detection, and limit of quantification. Therefore, an evaluation of these effects should be involved in validation of every single LC-MS method and their source should be eliminated. The assessment is generally performed by qualitative and quantitative approaches such as post-extraction addition, post-column infusion, and comparison of slopes of calibration curves. The matrix effects can be reduced or...

International railway transport of goods in the Czech Republic and Slovakia
Asman, Tomáš ; Zelený, Lubomír (advisor) ; Havlis, Jan (referee)
The goal of my thesis is to analyze the current situation in the market of rail freight transport and to find the potential of the international railway transport of goods in the Czech Republic and Slovakia. It is focused on the comparison of these countries. Main topics of this thesis are i. a. the competitive environment in the Czech and Slovak railway, combined transport, system trains and the expected future progress.
