Entry knowledge

Basic knowledge of physics - kinematics, the movement of charged particles in magnetic and electric field
Good knowledge of basic, inorganic, organic, physical and analytical chemistry

Rules for evaluation and completion of the course

The exam consists of a written and oral examination. The subject of the written interpretation of the given mass spectrum, the oral examination is focused on the verification of student's knowledge in the range of themes discussed in the lectures. In the final assessment, the result of the written part contributes by 40%, the result of oral part by 60%.
Attendance at lectures is optional and is not controlled, but it is recommended.

Aims

The aim of this course is:
- to familiarize students with the theoretical foundations of mass spectrometry
- to provide an overview of current instrumentation of mass spectrometry
- to introduce students to the basic concepts interpretation of mass spectra
Successful completion of the course the student will gain the following knowledge and skills:
1. Students will be familiar with the principles of functions of various types of mass spectrometers;
2. Students will be able to choose the optimal device for highly efficient solutions for specific analytical problems;
3. Students will know the basics of mass spectra interpretation, depending on the ionization technique used and the analyzer resolution.
