Within this course, principles and key applications of modern isolation, separation and detection techniques commonly used in the field of studies / characterization of biologically active compounds. Special attention is paid to (i) application of basic and advanced extraction techniques; (ii) effective separation strategy realized by gas / liquid chromatography; (iii) presentation of various instrumental techniques with a special focus on mass spectrometry and its presentation in case studies. In the final phase of course, practical aspects together with problems to be solved in a qualified manner in practice are summarized.
