China Wholesale Raman Factory – LADP-1 Experimental System of CW NMR – Advanced Model – Labor Detail:

Nuclear magnetic resonance (NMR) is a kind of resonance transition phenomenon caused by electromagnetic wave in a constant magnetic field. Since these studies were carried out in 1946, the methods and techniques of nuclear magnetic resonance (NMR) have been rapidly developed and widely used because they can go deep into the substance without destroying the sample, and have the advantages of rapidity, accuracy and high resolution. Nowadays, they have penetrated from physics to chemistry, biology, geology, medical treatment, materials and other disciplines, playing a huge role in scientific research and production .

Description 

Optional part:Frequency meter, self prepared part oscilloscope

This experimental system of continuous-wave nuclear magnetic resonance (CW-NMR) consists of a high homogeneity magnet and a main machine unit. A permanent magnet is used to provide a primary magnetic field superimposed by an adjustable electromagnetic field, generated by a pair of coils, to allow a fine adjustment to the total magnetic field and to compensate magnetic field fluctuations caused by temperature variations.

Because only small magnetizing current is needed for relatively low electromagnetic field, the heating problem of the system is minimized. Thus, the system can be operated continuously for several hours. It is an ideal experimental instrument for advanced physics laboratories.
