MULTIFUNCTIONAL SYSTEM FOR ENERGY-DISPERSIVE X-RAY-FLUORESCENCE ANALYSIS

A multifunctional energy dispersive x-ray fluorescence (EDXRF) system has been set up. It comprises three measuring lines, each utilizing a different mode of x-ray fluorescence technique. They are: total-reflec tion x-ray fluorescence (TXRF), x-ray microfluorescence (XRMF) with th e use of capillary optics and the XRF bulk sample analyzer As a source of primary radiation a diffraction x-ray tube has been applied. Three x-ray beams can be utilized at the same time. The system has been dev eloped to be applied mostly for the analysis of environmental and geol ogical samples. For the study of water pollution by unwanted heavy met als at ppb concentration level the TXRF is used. This method can also be applied for analysis of digested biological samples. The microfluor escence is a unique XRF technique for air particulate analysis and ele mental imaging of biological, and geological materials. The preliminar y results of micro-fluorescence analysis will be presented.
