Summary
The course is focused on broadening and deepening the knowledge of modern instrumental laboratory techniques, including gaining practical skills. The aim of the course is to provide students with a solid and sufficiently broad theoretical and methodological basis for methods of instrumental analysis, both inorganic and organic. The main focus of the lessons is the interpretation of the theoretical foundations of instrumental methods of analysis. Practical exercises emphasize students' independent approach to solving analytical problems of selected instrumental methods.
