Annotation -
The course of separation methods gives compendium on modern separation methods from the theoretical and practical point of view. The course explains the general theory of separation and a summary of physico-chemical principles such as transport phenomena, solubility, adsorption, ion exchange, exclusion effect, biological recognition. Theory of chromatography and of electromigration. Systematic description of important separation techniques. The course ends through a written exam.

Learning outcomes: After completing the course, the student will be able to define basic terms, clarify the theory of separation processes, differentiate interaction forces in separation methods, perform extraction, explain solid phase extraction, clarify supercritical fluid extraction, define affinity chromatography, define ion exchange chromatography, define gel permeation chromatography, perform gas chromatography, explain supercritical fluid chromatography, perform liquid chromatography, perform paper chromatography, perform thin-layer chromatography, explain electromigration, explain the overview and division of electromigration methods and perform capillary electrophoresis.
