Magnets used in NMR spectrometers

Keywords: magnets, NMR spectrometers, permanent magnets, Neodymium Magnets

 

Nuclear Magnetic Resonance (NMR) spectroscopy is an analytical chemistry technique used in quality control and research for determining the content and purity of a sample as well as its molecular structure.

 

NMR spectrometers have a very strong, large and expensive liquid helium-cooled superconducting  magnet, because resolution directly depends on magnetic field strength. Less expensive machines using permanent magnets(such as Neodymium Magnets) and lower resolution are also available, which still give sufficient performance for certain application such as reaction monitoring and quick checking of samples.

 

The most common types of NMR are proton and carbon-13 NMR spectroscopy, but it is applicable to any kind of sample that contains nuclei possessing spin.

 

Magnets create request magnetic field in NMR spectrometers.
