Vývoj, optimalizace a validace analytické metody na stanovení těkavých mastných kyselin ve vodných vzorcích metodou GC/MS
 OPEKAR, Jan
This thesis is focused on the development of an analytical method for the determination of volatile fatty acids in aqueous samples using GC-MS/MS. The theoretical section provides general information on a selected group of acids, their significance in the biogas plants, the means of their derivatization and the analytical techniques used. The practical part mainly deals with optimizition of various parameters in the derivatization reaction to achieve optimal conditions. Finally, the analytical method was successfully validated and applied to the analysis of a real sample.

Establishment of method for determination of selected triazine pesticides in water using GC-MS/MS
 OPEKAR, Jan
This bachelor thesis deals with the determination of triazine pesticides in water using GC-MS/MS. Firstly, the development and optimisation of an analytical method was performed. The following parameters of the analytical method were chosen for optimisation: carrier gas flow rate, temperature gradient, selection of SRM transitions and collision energy of SRM transitions. Then, several extraction parametres such as SPE column drying time, selection of elution solvent, sample pH and sample volume were optimised. Finally, the method was successfully validated and applied to the analysis of a real tap water sample.
