An experimental unit has been developed for energy-dispersive X-ray fluorescence analysis allowing the preliminary selection by the sample emission energy. Possibilities offered by the unit in multicomponent qualitative analysis, quantitative analysis of Ca, Sr, Rb, Bi, Cu oxides as well in the operating zone air pollution monitoring have been studied. The use of high-power X-ray tubes in combination with the scheme of the sample emission energy preliminary selection is shown to be effective in determination of low element concentrations. Application of Bragg type reflectors shaped as a curved LiF(200) single crystal and as composed cylindrical reflector consisting of LiF(200) segments allowed to assure almost one decimal order lowered detection limits for Zn and Se in the air analysis.
