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 IX, 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 IK is measured and the concentration of the investigated element СX is determined according to the formula: СX=IXCK/(IK-IX) where CX is the concentration of the investigated element; IX – signal of the detector of the investigated element; СK is the concentration of the introduced element; IK – signal of the detector of the introduced element.
EFFECT: invention makes elemental analysis of the composition of substances more effective
