METHOD FOR MEASURING QUALITY OF OIL PRODUCTS Russian patent published in 2014 - IPC G01N24/00 

FIELD: measurement equipment.

SUBSTANCE: use: for measuring of product quality. Substance: consists in the fact that in the process of measuring of remote NMR spectra of several reference oil products with known values of quality indicators covering the full range of possible changes, the fixed principal chemical shift determines the position of the absolute maximum of the NMR spectrum of each oil product, characterised by the fact that on the basis of shot spectra they determine analytical dependence linking the normalised values of each of the quality with the main chemical shift of the reference oil product, which is stored in a processor, the measured NMR of the controlled product that captures the main chemical shift q_X. After that, each specific indicator of fuel quality is determined by the dependence connecting with the main indicator of quality with the chemical shift. The dependence is determined during calibration according to reference oil.

EFFECT: providing opportunities to facilitate measurements of quality of oil products without compromising accuracy.
