Abstract
The article presents the results of studying of nuclear magnetic relaxation characteristics of protons, which contain in various organosilicon fluid brands, with the aim of justifying the possibility of their use in the development of simulator reference materials (RMs) of oleic acid mass fraction in sunflower seed oil. The data characterizing the NM-relaxation characteristics of organosilicon liquids, varying in a viscosity index, are provided. Based on the range of changes in the time of spin-spin relaxation of protons containing in oil of sunflower seeds with various mass fraction of oleic acid (157-200 msec) there are select silicon organic fluids, that allow the most accurate simulation of wave-form envelopes of oil protons spin echo signals in the seeds. The simulator reference materials under development are intended for use in the calibration of NMR-analyzers for determination of oleic acid mass fraction in of sunflower seed oil.
