Course objectives
Main objectives can be summarized as follows: Fundamentals and practice of basic separation methods used in organic chemistry (crystallization, distillation, sublimation, extraction, etc.) with focus on chromatographic methods; membrane separation processes and electromigration methods are mentioned as well.
Learning outcomes
After accomplishing the course students will be able:
- to understand and explain principles of the separation methods frequently used in organic chemistry in particular (e.g. GC, LC, HPLC, TLC and their modifications, crystallization, distillation, sublimation, extraction and electromigration methods);
- to choose appropriate separation method for solution of common analytical or preparative problems;
- to apply the knowledge obtained for setting basic parameters of the mentioned methods for development of simple procedures for sample separation.
