In lectures, students learn about modern methods of trace element analysis based on the principles of atomic spectroscopy. Introductory part of the course is devoted to theoretical principles, the structure of the atom, energy transitions in the electron shell of atoms and basic structural elements used in atomic spectroscopy. The main part of the course comprises atomic absorption spectroscopy, which is currently the most widely used technique of elemental analysis. Students learn the used radiation sources, methods of atomization interference correction methods and some special approaches to the analysis (generation of volatile compounds, electrolytic deposition of analyte). Another series of lectures is devoted to emission spectral analysis, students will learn various methods of excitation spectra, such as spark, arc, glow discharge, plasma and laser. Attention is also paid to the atomic fluorescence spectroscopy, the X-ray, electron and mass spectroscopy. In the lectures on applications, students get acquainted with work in the trace lab, use of coupled techniques for speciation analysis, the methods of preparation of various types of samples (water, biological materials, ores and rocks) and the possibilities of using atomic spectroscopy techniques for in situ analysis.
