Special Methods of Instrumental Analysis

The aim of the subject is to deepen the knowledge of students in analytical chemistry and to prepare them for solving analytical problems with use of instrumental methods. Emphasis is laid on the ability of students to select optimal methods and appropriate procedures with regard to the nature of the analysed object and to realize the scope and limitations of instrumental methods. Practical training is realized in 3- to 4-membered groups of students.
