X-RAY ANALYZER OF GOLD AND HEAVY ELEMENTS Russian patent published in 2017 - IPC G01N23/223 

FIELD: mining.

SUBSTANCE: usage: for X-ray spectral analysis of gold and heavy elements. Technical character of the invention lies in the fact that the X-ray analyzer of gold and heavy elements comprises X-ray tube with a side window as a radiation source, a sample holder, the detection device with detectors disposed in line, the recording apparatus, the inputs of recording apparatus are connected to the outputs of the detector, collimators and filters of primary and secondary beams, wherein the secondary beam collimator is designed with a plurality of holes or channels, thereby the sample holder is designed to install the sample with a flat or concave working surface of a cylinder, the X-ray tube axis is positioned in the plane perpendicular to cylinder, its focus is positioned at the generating line passing through the diametrically opposite cylinder point, wherein the secondary beam collimator is designed with beam dividers in the plane axial to theelectron beam.

EFFECT: invention provides uniformity and strength of the sample, improves efficiency and expand contrast of the spectra.
