Trained and authorized users may schedule and access the spectrometers (SSHD-500 and AV300) via iLab. However, such users are requested to contact the Facility staff before running their experiment to ensure that the spectrometer is ready to use. In particular, please ensure that the correct probe and filters are in place, magic angle is adjusted, probe is shimmed, tuned and matched to the required frequency. Unless requested otherwise, users are expected to do the chemical shift referencing with a standard sample for their nuclei of interest.
All other users will be provided with an assisted use. This includes spectrometer setup, chemical shift referencing with a standard sample and running the experiment. However, any assistance with sample preparation (e.g. packing the rotor) and post data analysis (e.g. quantitative analysis, spectral assignment etc.) will be charged separately at the consulting rate.
For assisted use, samples or packed rotors should be send to the facility director/NMR spectroscopist with a general description about the chemical properties of the sample and required experiments. In case the user is unable to determine which experiment is suitable for their purpose, users should kindly provide details about the type of information being looked for and the corresponding literature.
Users are permitted to borrow rotors, drive tips and packing tools from the NMR facility. Please watch this video
to learn how to pack a rotor. All tools should be returned promptly in good condition. Users must compensate the NMR Facility for any loss or damage caused due to their fault.
Air sensitive samples must be packed inside a glove box and should be sealed with an airtight drive tip that has an O-ring. Samples that are explosives or could potentially explode under magic angle spinning conditions (due to heat or stress) should not be used.
Solid state NMR service on the 850 multi-purpose spectrometer is provided based on demand. Please check with the staff for the availability of this spectrometer for SSNMR.
