FAQ's

Is there a submission form to fill out when I drop off my samples?
The sample submission form for external users: External Users and for internal Users: Internal Users

Are there instructions on how to use the 300MHz and 400MHz spectrometers?
Yes there are! The 300's operating procedure , and the 400's operating procedure

What are the booking rules for the spectrometers?
All the answers to your questions on booking your favorite spectrometer can be found in the document titled: Booking Rules

How do I use the POPT command?
Obtain the instructions from the POPT document.

How much sample do I need?
Dissolve 5 to 100 mg of sample in 600 microlitres  of  a deuterated solvent. The amount depends on the experiment. Proton requires much less than carbon, for example. The column height in the NMR tube should be 4 cm.

How do I prepare the sample to get the best results?
Make sure the sample does not contain any insoluble particles. Filter if necessary. Use good quality NMR solvents. Some solvents, like DMSO and D2O get 'wet' unless tightly sealed and the water peak in the spectrum can obscure areas of interest. Using a single ampule for each sample works best. These are available in stores.

What kind of NMR tube should I use?
Stores sells Wilmad 507pp tubes for routine samples and 528pp tubes for important samples where very good resolution is required. Generally recommended for the 600's and the 800. Take good care of the tubes. Do not bake them in a hot oven to dry, or they will warp. If it is necessary to dry them, use a warm oven, and lay them flat.

How do I pack my MAS sample rotor?

How did you get the 800 into the lab?
The window in the side of the building, the doors to the lounge and lab were all removed. For the full story see here: Birth of an 800.
