METHOD FOR ANALYZING ATOMIC COMPOSITION OF DISPERSED POWDER MATERIALS Russian patent published in 2021 - IPC G01N21/67 

FIELD: elemental analysis.

SUBSTANCE: invention relates to methods for elemental analysis of the composition of substances and can be used to analyze the composition of powder samples. The method for analyzing the atomic composition of dispersed powder materials includes the evaporation of material by laser radiation, feeding this material into a plasma torch of an HF discharge with a working gas flow, spectral analysis of the radiation of the sample material, determining the signal amplitude of the detector of the investigated element I_X, while at the stage of sample preparation, the material is introduced in the form of powder the investigated element with the concentration of С_К. After that the signal amplitude of the detector I_K is measured and the concentration of the investigated element С_x is determined according to the formula: С_Х=I_XC_K/(I_К-I_Х) where C_X is the concentration of the investigated element; I_Х - signal of the detector of the investigated element; С_К is the concentration of the introduced element; I_К - signal of the detector of the introduced element.

EFFECT: invention makes elemental analysis of the composition of substances more effective.
