Vývoj, optimalizace a validace analytické metody na stanovení kyseliny chikorové a dalších derivátů kyseliny kávové pomocí LC/MS
Abstrakt
This thesis deals with the development, optimization, and validation of an analytical method for the determination of chicoric acid and other caffeic acid derivates using LC/MS. First, the development and optimization of the analytical method was conducted. The following parameters were selected for the optimization: mobile phase composition and flow rate injection volume capillary temperature, voltage S-lens and F-lens voltage, ion injection time, product ion selection, and collision energy. Then, the analytical method was successfully validated and tested for quantitative analysis in a range of Echinacea food matrixes - tea, tablet, and tincture.
