This master thesis deals with the development, optimization and validation of an analytical method for determination of neurotoxin -N-methylamino-L-alanine in pond water and cyanobacteria using LC/MS. Firstly, basic parameters of the analytical method developed within authors´s bachelor thesis were verified. Following parameters were selected for verification: selection of suitable MRM transitions, voltage applied to S-lens and F-lens and standardized collision energy. Secondly, the system suitability testing was performed. Thirdly, the analytical method was successfully validated. Then, the testing and optimization of solid phase extraction for analysis of water samples were carried out. The pH of sample solution and composition of elution solution were chosen for the optimization. In addition, the trichloroacetic acid extraction with acid hydrolysis for cyanobacterial samples was carried out too. Finally, both solid phase extraction and trichloroacetic acid extraction were evaluated and applied to the analysis of real samples.
