SIMULATOR OF FREE PRECESSION SIGNALS OF NUCLEAR MAGNETIC RESONANCE AND SPIN ECHO FROM OIL AND PHOSPHOLIPIDS IN RAPE LECITHIN Russian patent published in 2021 - IPC G01N24/08 

FIELD: chemistry.

SUBSTANCE: invention can be used for calibration and verification of NMR-analyzers for quantitative determination of content of phospholipids in rape lecithin. Essence of the invention lies in the fact that simulator of free precession of nuclear magnetic resonance and spin echo from oil and phospholipids in rape lecithin includes polymysiloxane liquid of GTMS-5000 type with spin-spin relaxation time of 130–160 ms, PES-5 polyethylsiloxane liquid with spin-spin relaxation time of 30–40 ms and natural latex with spin-spin relaxation time of 2–4 ms, wherein the amount of PMS-5000 grade polymethylsiloxane liquid is 1.05–1.34 g, and amount of natural latex is 2.75 g.

EFFECT: technical result is enabling possibility of reproducing with high accuracy shape envelope signals of spin echo of oil protons and phospholipids in rape lecithin.
