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

I'm a new user; what do I need to know?
The new user document includes basic information on the NMR Centre, including required training and spectrometer scheduling.

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?
Only Wilmad tubes of grade 506-PP or higher are allowed for routine use. Please contact NMR staff prior to using any other kind of tube.

The tube must not be chipped, cracked, or warped in any way or else it could damage or break in the probe (costing thousands of dollars to repair). New tubes can be purchased from Stores (in Science Complex) or by contacting NMR staff.

(Aside - don't bake your tubes in a hot oven to dry, or they may warp. If it is necessary to dry them, use a warm oven, and lay them flat.)

How do I clean my NMR tube?
Read the informative paper How To: Clean NMR Tubes .

How should I label my NMR tube?
All NMR samples must be labelled with your name, your supervisor's name, sample ID, date of preparation, and solvent. Labels should NOT be taped to NMR tubes, and must be removed prior to inserting a sample in the magnet. You can download a NMR tube label template . NMR samples and tubes found without a label will be immediately disposed of as chemical waste by facility staff.

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.
