What is NMR?
Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful analytical technique used to determine the structure and properties of molecules. It involves applying a magnetic field to a sample and then measuring the radio frequency signals emitted by the nuclei of atoms within the sample.
Liquid nitrogen in NMR
Liquid nitrogen plays a crucial role in NMR spectroscopy, particularly in cooling the superconducting magnet used in the NMR spectrometer. This low-temperature environment is essential for maintaining the superconductivity of the magnet, which is necessary for generating the strong magnetic field required for accurate measurements.
Why choose liquid litrogen generators?
While traditional methods of supplying liquid nitrogen, such as dewars, have been used, liquid nitrogen generators offer several advantages:
- Continuous Supply: Generators ensure a constant supply of liquid nitrogen, eliminating the need for frequent refills and minimizing downtime.
- Reduced Maintenance: Compared to dewars, generators require minimal maintenance, saving time and resources.
- Improved Safety: On-site generation eliminates the risks of handling and transporting large quantities of liquid nitrogen.
- Environmental Benefits: Generators reduce the carbon footprint by eliminating the need for frequent deliveries and transportation.
- Cost-Effective: Long-term savings can be achieved through reduced operational costs and increased efficiency.
By choosing a liquid nitrogen generator, laboratories can optimize their NMR operations, improve efficiency, and reduce overall costs.
Liquid nitrogen generation on site
Superconducting magnets are the cornerstone of NMR spectroscopy. These powerful magnets generate incredibly strong magnetic fields that are essential for manipulating the spins of atomic nuclei. By subjecting samples to these intense magnetic fields, scientists can gain valuable insights into the molecular structure and dynamics of a wide range of substances.

To maintain their superconducting state, the magnets in NMR spectrometers must be cooled to extremely low temperatures, often below -269°C (-452°F). Liquid nitrogen plays a crucial role in achieving and maintaining these cryogenic conditions. By acting as a coolant, liquid nitrogen helps to shield the superconducting magnets from the warmer ambient temperature, ensuring their optimal performance and enabling the acquisition of high-quality NMR data.
