General policies

  • No food or beverages near the spectrometers.
  • Do not leave your NMR tube in the NMR facility.
  • If a sample breaks in the magnet, contact the NMR Facility Director immediately (by phone or in person) so the probe can be cleaned. Minimum information needed: name and structure of the compound if known, or at least class of compound, name of solvent, toxicity of material, and other solvents which dissolve it, special precautions in handing if it is toxic. Please leave a note on the instrument keyboard warning users not to use the instrument. This will minimize probe damage.
  • Repairs for any damage to the probes resulting from user error will be charged to the user group.
  • If there is problem, leave a note or contact the NMR Facility Director if it cannot be resolved by following Troubleshooting FAQ.
  • DO NOT TOUCH HARDWARE or REBOOT INSTRUMENT.
  • All users must lock and shim on the dummy sample and LOGOUT from your account when finished with the spectrometer. The dummy sample on the instruments is CDCl3. If the dummy sample breaks, contact the  NMR Facility Director so that it can be replaced.
  • READ THE MANUAL! You will find most of your questions are addressed in the 1D instruction manual.
