All NMR users need to finish the Basic NMR training classes before they are authorized to operate the spectrometers. The users are allowed to schedule their own times on the spectrometers on-line.
Please choose from the following for more information:
NMR Facility Usage Fees
All NMR Spectrometers will be using the following rates from July 1, 2011.
NMR Facility Scheduling Policies
The following operating policies are used for all spectrometers.
NMR Facility Training
Basic NMR classes are offered often during semesters. All users need to finish this class to be authorized to use the spectrometers. This class normally takes 3 to 4 sessions of 90 minutes to 2 hours. An email will be sent in advance about the meeting of this class. All students are encouraged to finish these classes well before starting the research work in the lab. Users can find a step-by-step operation of the spectrometer in the Tutorials section.
NMR Sample Preparation
The quality of your spectrum is greatly affected by the sample preparation.
Please use good quality NMR tubes. Etched NMR tubes should not be used.

Safety Issues with Superconducting Magnets
Metal Objects, Pacemakers, Credit Cards, and Watches
The magnets on all the NMR spectrometers are very strong. They can pull metal objects out of your hands or pockets. Therefore, there is a risk of injury to the user when a metal object is attracted to the magnet(a friend's wrist was broken when a magnetic stirrer was pulled to the magnet). In addition, the metal objects can lead to extensive damage to the instrument. The metal objects do not need to be large: objects as small as staples and paper clips can cause serious damage to a spectrometer.
Pacemakers may misfunction in the presence of the magnetic field. It is advised that persons with pacemakers do not go near NMR spectrometers. Please make arrangements with the NMR staff or other co-workers to acquire NMR data. Remember, the magnetic fields of the spectrometers are reasonably strong a considerable distance from the magnet.
Credit cards will be erased by the magnetic field. Watches may be damaged by the magnetic field. Do not bring credit cards and watches in the NMR labs.
Magnet quenches occur very rarely but can have very serious consequences. A 'quench' is the spontaneous loss of the superconducting quality of the magnet. This causes the inner core of the magnet to become very hot and results in a rapid boil-off of the liquid nitrogen and liquid helium in the dewars surrounding the magnet. Typically, a quench produces a very loud constant noise and a large white plume from the top of the magnet. During the quench, oxygen is frozen out of the air and the room becomes filled with helium and nitrogen gas. Therefore, it is absolutely necessary to evacuate the room when a quench occurs. Quenches can not be predicted and, sometimes, not prevented.
