The subject is closely focused on the electroanalytical techniques and methods and provides knowledge about the methods with which it is possible to meet in practice. The first part of the course is focused on a common theoretical background to all the electroanalytical methods, redox potentials, thermodynamics, electron transfer, electric double layer, faradaic and charging currents, fabric transport, the kinetics of the reaction of electrode reactions and more. Another part of the series of lectures deals with the classification of the various methodologies and experimental aspect of electroanalytical methods, general principles of individual determination and description of the instrumentation, so that the students get on overview of this area. Other lectures then discussd potenciostatické method, and the polarographic techniques from voltammetric classic Heyrovského arrangement to various pulse methods, the use of the rotating disk electrodes and ending with alternating current voltammetry measurements including second harmonic frequency. The next part of the course deals with the amperometry and follows the methods based on electrolysis and accumulation of analytes, thus stripping techniques and electrogravimetry. In addition, attention will focus on the galvanostatic and potenciometric methods, followed by electroimpedance spectroscopy. The last part is devoted to modern application possibilities, in particular the sensors which are used both in industry and in the clinical analysis and combinations of electroanalytical techniques with other methods (HPLC, in-situ spectroelectrochemistry, etc.).
