More details about the invention

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 includesthe 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 СК. 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_X=I_XC_K/(I_K-I_X) where C_X is the concentration of the investigated element; I_X – signal of the detector of the investigated element; С_K is the concentration of the introduced element; I_K – signal of the detector of the introduced element.
EFFECT: invention makes elemental analysis of the composition of substances more effective
