Desktop nuclear magnetic resonance spectrometer

The 90M desktop nuclear magnetic resonance spectrometer effectively improves the chemical shift resolution and obtains chemical structure information from it. It has low maintenance costs (no need for liquid nitrogen or helium), can be used for organic chemical structure analysis and synthesis detection, and is suitable for general scientific research work. Mainly used for organic chemical structure analysis and on-site detection of fine chemicals. It can be used in fields such as chemical synthesis and drug analysis. The 90MHz nuclear magnetic resonance spectrometer adopts the "pulsed Fourier transform nuclear magnetic resonance" technology, which consists of parts such as "magnet", "electrical control", "pressure source", and "deuterium lock".

It can be used in fields such as chemical synthesis and drug analysis. The 90MHz nuclear magnetic resonance spectrometer adopts the "pulsed Fourier transform nuclear magnetic resonance" technology, which consists of parts such as "magnet", "electrical control", "pressure source", and "deuterium lock". The use of constant temperature control results in high stability, and the use of a uniform field power supply and pneumatic rotating probe can achieve high resolution.
