Cryogen Safety

Note that superconducting NMR magnets contain liquid helium and liquid nitrogen and are filled with these liquids on a regular basis.

Magnet Quench

The sudden boil-off of these cryogens (and loss of magnetic field) is called a quench. A quench is an extremely unlikely occurrence under normal circumstances. However, please note the following:

Using liquid Nitrogen for VT NMR experiments

Please refer to the saftey office pages if handling liquid N2.
