ANALYTICAL APPLICATION OF MULTIFUNCTIONAL SYSTEM OF EDXRF

The applications of multifunctional energy dispersive x-ray fluorescen ce system have been described. Application of micro-beam x-ray fluores cence technique using capillary optics for the quantitative analysis o f titanium and bismuth distribution in glass samples has been shown. T he samples of glass made of GRIN materials have been scanned along the ir diameters and the distributions of the concentrations of TiO2 and B i2O3 admixtures have been determined. Total reflection x-ray spectrome try was applied for the determination of minor and trace elements in m inute samples (ca. 10(-5)g) of medieval pigments. The knowledge of pig ments chemical composition can facilitate to find the source of their origin. The malachite and azurite were analyzed. The broad x-ray beam from yttrium secondary target was used for the analysis of urban dust collected on filter surface. The detection limits and accuracy for iro n, zinc, copper and bromine have been established.
