In lectures, students learn about modern methods of trace element analysis based on the principles of atomic spectrometry. 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 spectrometry. The first part of the course comprises atomic absorption spectrometry. 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 concerned with emission spectral analysis, students will learn various methods of excitation of spectra, such as spark, arc, glow discharge, plasma and laser. The following part of the lectures if concerned with inductively coupled plasma mass spectrometry, the students will learn the basics of instrumentation, methods of correction of spectral and non-spectral interferences and special techniques, such as elemental speciation analysis, single-particle analysis and isotope dilution. Attention is also paid to the atomic fluorescence spectrometry and the X-ray spectrometry. In the lectures on applications, students get familiar with work in the trace lab, the methods of preparation of various types of samples (water, biological materials, ores and rocks) and the possibilities of using atomic spectrometry techniques for in situ analysis.
