X-ray fluorescence spectral analysis (hereafter referred to as "XRFA") based on photon excitation of atom inner electron shells and recording of X-ray fluorescence is one of the most important express instrumental methods of the analysis. Each chemical element is characterized by a set of spectral lines reflecting the availability of this element; while their intensity is directly connected with the element concentration.
Energy Dispersive X-Ray Fluorescence Spectrometer BRA-135F is able to detect simultaneously about 20 chemical elements less than 200 sec
X-ray radiation of low duty X-ray tube converted by primary radiation filters excites the fluorescence radiation of atoms of the sample under examination. Radiation flows (primary radiation scattered on the sample and secondary fluorescence radiation) comes in proportional gas meter and sulphur atom fluorescence radiation (SKa) is separated from radiation with other energies by means of selective filters.
X-ray wavelength dispersive sulphur analyser ASW-2 is used for the measurement of mass concentration of the sulphur in un-leaded gasoline, diesel oil, crude oil, kerosene, petroleum residues, lubricating oil, hydraulic oil, jet engine fuel and other types of cutter oil.
Analyzer AR-35 is designed for continuous X-ray fluorescence on-stream analysis of solutions, suspensions and pulp products of ore processing. AR-35 can simultaneously measure the concentration of 8 (eight) chemical elements in the processed product thus saving time and reducing cost of element identification.
Specialized wavelength-dispersive XRF analyzer based on the Cochois scheme is designed for high-precision determination of chemical elements U, Th, Mo, Au, W, Tl, As, Pb as well as other elements in ores, rocks and when developing the technogenic fields.
