Course objectives
In these classes, we will systematically introduce the main analytical methods using the separation of analytes in the electric field. Special attention will be devoted to the acquiring of the principles of the discussed methods and their employment in analytical praxis. The lectures will be held by highly experienced researchers with rich practical experiences.
Learning outcomes
A student knows the principles of the behaviour of analytes in the electric field and knows the main factors, which influence this behaviour. The student understands these principles in the context of discussed analytical methods.

Teacher's information
http://www.iach.cz/cs/
The lectures are given by respected scientists specialized in electromigration methods. All of them are employees of Institute of Analytical Chemistry of the CAS (IACH), where electromigration separations belong to well-established tools used for the research.

Therein, the demonstration of some discussed methods is possible upon request.

The course is also listed under the following terms Spring 2023, Spring 2024.
