Monitoring neurotoxinu \recke{beta}-N-methylamino-L-alaninu v povrchových vodách
PIXA, Jan
This bachelor thesis describes common information about cyanobacteria and cyanotoxins, environmental drivers of cyanobacterial blooms and summaries present knowledges of the occurrence of their secondary metabolite neurotoxin \recke{beta}-N-methylamin-L-alanin. The thesis includes a project proposal regarding monitoring of neurotoxin \recke{beta}-N-methylamin-L-alanin in fishponds and water reservoirs.
Vývoj, optimalizace a validace analytické metody na stanovení neurotoxinu \recke{beta}-N-methylamino-L-alaninu ve vodě pomocí LC/MS
HOŘEJŠÍ, Karel
This bachelor thesis deals with the development, optimization and validation of an analytical method for determination of neurotoxin \recke{beta}-N-methylamino-L-alanine in water using LC/MS. At first, the development and optimization of the analytical method was performed. For the optimization of the analytical method following parameters were selected: temperature of HESI and MS capillary, gases flow rate, voltage on S-lens, F-lens and capillary, collision energy. In addition, mobile phase composition, flow rate of mobile phase and injection volume of sample were optimized too. Then, the analytical method was successfully validated. Finally, the method was applied to the analysis of real samples of surface water.
