Patent ID: 6946837

Claim:
A method of determining the amount of fat/oil in a multicomponent sample system using nuclear magnetic resonance spectroscopy, comprising the steps of: a) providing a sample containing a multicomponent system, b) placing said sample in a nuclear magnetic sprectroscope, c) applying a homogenous/static magnetic field affected by an oscillating magnetic field, and a magnetic field gradient in a multi-pulsed magnetic field gradient spin echo experiment to said multicomponent sample, wherein said applied gradient is the same gradient strength throughout said experiment, d) measuring changes in nuclear magnetic moment(s), vector(s)/spin(s) of a group of protons in said multicomponent sample, e) adjusting said measured signal from said sample at the first echo by suppressing the contribution from the non-fat compounds in said multicomponent system by fitting said measured signal as a function of the number of echoes, and f) thus obtain a spectrograph of the amount of fat/oil at zero observation time.
