Abstract
The present invention is directed to a method of species identification and quality detection of liquid-like samples based on nuclear magnetic resonance technology. In this invention, a two-dimensional relaxation signal containing the 1H T1 and T2 relaxation properties of liquid-like samples is obtained by applying a composite pulse sequence to samples, and from this a fingerprint spectrum is established. The fingerprint spectrum can be associated with the essential characteristics of the tested sample, thus can be used to distinguish a specific liquid-like sample from the others.
