METHOD OF DETERMINING QUANTITATIVE CONTENT OF COMPONENTS IN ANALYZED MIXTURES BY PROCESSING DATA OBTAINED BY NUCLEAR MAGNETIC RESONANCE DURING RAPID MONITORING OF THEIR STATE Russian patent published in 2021 - IPC G01N24/08 

FIELD: physics.

SUBSTANCE: use: to determine the quantitative content of components in the analyzed mixtures by processing data obtained by nuclear magnetic resonance. Essence of the invention consists in that times of longitudinal and transverse relaxation of the sample, obtained by standard methods on an NMR spectrometer or relaxometer, are used to solve phenomenological Bloch equations taking into account conditions of their recording, after which the qualitative composition of impurities and their volumes is selected such that solutions of the Bloch equation for the analyzed mixture coincide with the solution obtained for the modeled mixture, taking into account the different contribution of impurities present in the mixture to absorption and dispersion signals, as well as specificity of nuclear magnetic resonance signal generation from mixture formed by substances similar in chemical composition and physical structure, thereafter, the quantitative content of impurities in the analyzed mixture is determined from the coefficients for different admixtures of the modeled mixture.

EFFECT: possibility of determining the quantitative content of components in the analyzed mixtures using longitudinal and transverse relaxation time parameters of the sample, obtained using standard methods on an NMR spectrometer or a relaxationometer.
