X-RAY SPECTRUM ANALYSER FOR IDENTIFYING AND SEPARATING MATERIALS Russian patent published in 2010 - IPC H05G1/00 G01N23/22 

FIELD: chemistry.

SUBSTANCE: invention relates to various fields of science and equipment for identifying such materials as separate organic compounds, organic polymers and articles made from said materials, elements of the first groups of the periodic table from H to F, for quantitative analysis of 2-3-component systems based on said elements, for determining the ratio C:H in hydrocarbons, as well as for separating materials consisting of light elements, for example as a coal separating sensor on a conveyer belt. The invention can be used in devices for identifying, analysing and separating objects and materials consisting of low-atomic number chemical elements, based on measurement of intensity of scattered X-rays. The anode of the X-ray tube in the disclosed device is made from titanium and the analyser has an extra detector lying between the analysed material and a recording system, before which there is a selective filter made from scandium.

EFFECT: higher accuracy of measuring effective atomic number of a medium and low cost of the device.
