With developments in both methodology and instrumentation in the past two decades, NMR has become one of the most powerful and versatile spectroscopic techniques for the analysis of chemistry, physics, materials science, biomedicine,life science .

Sensitivity and resolution are the most important indicators of an NMR system. In the final analysis,these are related to the homogeneity and stability of the magnetic field.

Most NMR spectrometers are using high-field Superconducting magnet that afford extremely stable external magnetic fields capable of acquiring data for extended periods of time. If the external field is generated by permanent magnets, as is the case with benchtop NMR spectrometers, the field can be less stable. Permanent magnet materials have characteristic temperature coefficients – meaning that a spectrometer’s magnetic field will respond to changes in temperature.

Use high-performance permanent magnet materials,no refrigerant, low cost, low maintenance cost, saving hundreds of thousands of operating costs every year

After careful design and manufacture, the system stability is less than 1PPM/Hour, and the homogeneity is less than 1ppm without active shimming.
