Development and its potential application of low-field nuclear magnetic resonance instrumentation

In this paper some basic components,performances and main technical problems of the 1.5T nuclear magnetic resonance(NMR) instrumentation which was developed by our group were introduced.This instrumentation was composed of permanent magnet,electronic parts and software,which was small,high ratio of signal-to-noise,non-destructive,economical and convenient be to used.Simultaneous,the stability of this instrumentation was also investigated.The signal to noise ratio of 1.5 T NMR was ten times than that of 0.5T NMR,and the sensitivity of 1.5T NMR was largely improved.Additionally,application of NMR in non-destructive analysis and biochemical analysis were also presented.With the successful development of 1.5T NMR,the technology of NMR has been greatly improved in our country,and 1.5T NMR will act as a novel instrument for the potential application in the field of biochemical analysis such as food quality control and safety,medical diagnosis,biomarker screening and so on.
