Instrumental Methods

The aim of the subject is to provide the students with firm and sufficiently wide theoretical and methodological fundamentals for pursuing (in a rational way) instrumental analysis of inorganic and organic substances. The teaching is focused on the explanation of theoretical aspects of instrumental methods and putting the accent on problem-solving tuition. In practical training individual approach of students to solving analytical problems is required.
