Course objectives
Separation methods play significant role not only in analytical chemistry but also in all other chemistry branches, in chemical and biochemical technology and pharmaceutical industry. Capillary electrophoresis is modern separation method and one of the most efficient separation techniques, generally. The main advantage besides its high efficiency is low consumption of the sample and possibility to separate even very similar compounds and various isomers including the chiral ones. The main goal of the course is to explain the students the basic principles in such way that they would be able on the base of gained knowledge to use rationally the technique in real practice and to know how to apply it even to the separation problems not described in the literature: for separation and determination of inorganic, organic, pharmaceutics and drugs and also to use it in other branches like biology, medicine and technology. Therefore, part of the course is also practical exercise and problem solving on a computer and simulation programs afforded with extensive database of compounds, theirs physico-chemical constants, etc. which allows to learn the students to think. The course is also accompanied with basics of the electrophoretic methods development and optimization including the use of a combination of the experimental design and with the use of artificial neural networks.
Learning outcomes
Student after passing the subject should be able: - understand principals of individual modes of capillary electrophoresis (CE);
- should be able to explain basic principals of CE also to friends and other students;
- propose the suitable method of separation for given analytes and explain why;
- to understand basic principals of detection in CE and should be able to recommend suitable detection method for given class of compounds;
- especially, he should understand basic principal of in-direct detection in CE and propose for given type of analytes suitable method of indirect detection;
- to understand databases of compounds properties in the literature(pK, mobilities, etc.) and be able to use the data I n the proposal of separation of given compounds by ;
