APPLICATION OF CAPILLARY ZONE ELECTROPHORESIS FOR ATMOSPHERIC AEROSOLRESEARCH

The capillary zone electrophoresis (CZE) was applied to analyze atmosp heric aerosol samples collected by a cascade impactor and filters. A W aters Quanta 4000 system equipped with data acquisition and evaluation software as well as with an indirect UV detector of fixed wavelength was used. Calibration curves were prepared by means of standard stock solutions to qualify and quantify different inorganic and organic ions . The detection limit and sensitivity in the case of each ion were car efully determined. On the basis of data obtained the size distribution of the ions in aerosols and the composition of particles in the fine particles size range were studied. Correlations were calculated betwee n concentrations and light scattering coefficient.
