Abbreviation of location of studies: Kém.

Description of the research topic:

In this research, we plan to develop and study a monitor-type analyzer system for the determination of the metal content of atmospheric aerosols, even under field conditions. This analytical arrangement is a combination of an electrostatic precipitator (to be used for the trapping of aerosol particles) and a direct current glow discharge (to be used for the vaporization of the trapped aerosol samples by cathode sputtering, followed by atomization, excitation and emission detection). The main aim of this work is to assembly the measurement system and to study its fundamental features and on the base of this, to optimize the operating conditions (e.g.: aerosol sampling rate, trapping efficiency, plasma parameters), which are the most favourable for the fast monitoring of the metal composition of atmospheric aerosols.)
