Magnetic resonance lab (NMR/EPR)

About Us

Nuclear magnetic resonance (NMR) is a spectroscopic technique that probes molecular structure by aligning atomic nuclei in a magnetic field and measuring their response to radiofrequency pulses

General guidelines and policies

No food or beverages are allowed in the NMR lab.
No sample preparation in the NMR lab.
On finishing your NMR session, leave the workstation organized. Do not leave NMR tubes, gloves etc. in the NMR lab.
All NMR sessions have to be recorded in the spectrometer notebook including errors/special issues.
It is forbidden to download softwares/play games on the NMR computers.
6. All users must follow the scheduling restrictions (allowed sign-up and cancellation) and register in advance. The guidelines are found in the NMR reservation site.
Do not change the NMR probe or reconnect any RF cables.
Non-standard experiments requiring the assistance of the NMR lab staff have to be scheduled with them in advance.
If a sample breaks in the magnet, contact the NMR lab staff immediately so the probe can be cleaned.

Users are allowed to work independently on the NMR instruments only after receiving proper training and having an active user. It is forbidden to work with someone else's user!
Users from the Chemistry department that will use the NMR on a regular basis have to contact Inbal to schedule their training sessions.

Liquid nitrogen fills are performed once a week on Monday morning (8:00-10:00).
Liquid helium fills are performed once in three months.

Every user must be familiar with the safety considerations regarding the use of a NMR spectrometer!

These concerns are the presence of strong magnetic fields and cryogenic liquids.

People with medical implants (such as cardiac implants pacemakers, aneurysm clips, surgical clips or prostheses) should check with the NMR staff before entering the NMR lab.
All metallic and magnetic objects must be kept away from the NMR spectrometer. This includes keys, wallets, magnetic cards, mechanical watches, tools, etc. Assume any piece of metal is magnetic until proven otherwise.
If a magnet quench occurs, immediately evacuate the NMR room. A quench is a sudden evaporation of the magnet's helium and nitrogen which displaces air and can result in suffocation. It can be detected by visible and/or audible emission of cryogenicgs from the magnet.
In case a metallic object strikes the magnet, get the NMR Facility staff immediately. Do not attempt to pull the object off yourself.
