Course objectives
The main objective of the course is to obtain an overview and deeper knowledge in the field of atomic absorption spectrometry from basic principles, instrumentation, interferences and background correction to methods of atomization of elements. At the end of the course, students should be able to: - understand the problems in atomic absorption spectrometry (AAS) - characterize parameters important for measurement in AAS - choose system of elimination of interferences and background correction - compare capacities of flame AAS, AAS with electrothermal atomization and AAS with generation of volatile compounds - gain an idea of practical application of AAS.
Learning outcomes
The student is able to: - choose suitable technic (flame, electrothermal atomization) for AAS determination - describe parameters important for measurement in AAS - choose system of elimination of interferences and background correction by practical analysis.

Teaching methods
Education is performed as lectures with Powerpoint presentation. Understanding of basic principles of atomic absorption spectrometry, atomization in atomizers, interferences, their elimination, background correction and the use in practical analysis is emphasized.
Assessment methods
Final assessment (at the end of semester) is by oral examination. The exam consists in four questions, which require description and explanation of asked topic.
