METHOD OF DETERMINING ELEMENT CONCENTRATION AND PHASE OF SAID ELEMENT IN SUBSTANCE WITH COMPLEX CHEMICAL COMPOSITION Russian patent published in 2009 - IPC G01N23/20 G01N23/223 

FIELD: chemistry.

SUBSTANCE: invention can be used for determining concentration of an element and phase of the said element in a substance with complex chemical composition. A sample of analysed substance is exposed to monochromatic gamma- or X-rays. The following intensities are simultaneously recorded: primary radiation coherently scattered by the determined phase and primary radiation non-coherently scattered by the same sample. Concentration of the determined phase is established with respect to the said intensities. The said intensities are recorded at the same time as intensity of characteristic radiation of the determined element. Concentration of the determined element in the analysed sample is established from the ratio of intensity of characteristic radiation of the determined element to the intensity of radiation non-coherently scattered by the same sample.

EFFECT: design of a high-precision and high-speed method of determining concentration of an element and phase of the element in substances with complex chemical composition.
