NEVER remove samples from the autosamplers if they are in the queue (pink in the diagram).  Be very careful about the number of the position you remove!  If you do remove a sample that is yellow or green in the diagram, note down the number and put it in the same spot in the rack.  If there is no space, move one of the samples already in the rack to a position in the front where there is no number.

NEVER allow anyone who has not been trained to be in the NMR room on their own.  This is for safety and because I want to be sure that I know what is being told to new users.  Training is free and usually scheduled within a week of when it is requested.  Training can be requested at http://nmr.chem.mcgill.ca/training – please direct new members to this site.

The Varian 500 is currently set up to do 1H and 31P only.  Do NOT try to do 13C.  Read here for instructions on tuning.  Do NOT tune 31P.  More information about experiments is available here.

All rules are listed here.  Instrument signup rules are on the instruments page.

Contact me (email: robin.stein@mcgill.ca, phone 514 398-6219 – this goes to my cell phone) if there are any problems or if you have questions.

Notes on troubleshooting temperature-related problems on Varian instruments have been added and are available here.

The usual probe that we use on the Varian 500 is not working and so we currently have an inverse probe tuned to 1H and 31P.  You can run experiments using 1H and 31P on it.  Do not tune the 31P channel, only the 1H (blue curve in trtune).  Notes about using the spectrometer are available here and notes on tuning are here.

The main units in rooms 34, 35, and 37 will be removed and replaced in September. During this time, there will be no EPR. Solid-state NMR access is currently unclear. Liquid-state NMR access will probably be reduced because overheating will be likely.

The units in rooms 35 and 37 are up. All instruments are up except Varian 400 (broken) and Varian 500 (waiting until it is cooler, since there is no functional A/C directly in room 34).

Work will take place in room OM 37 next week. There will be no access to the QANUC 500 or the Varian 400 beginning at 4 pm on Sunday. Access to the Bruker 500 will be possible during evenings and weekends only.

NMR is Fun is back again! This year, the NMR facilities of Université de Montréal, UQAM, and McGill will hold two days of NMR training on June 12-13 at McGill University (Arts Building room W-120). Day 1 will be at a basic level and will cover basic NMR principles, instrumentation, and tips and tricks for 1D and 2D NMR. Day 2 will be more advanced and will cover selective experiments, DOSY and relaxation, and exchange NMR and NOESY/ROESY techniques. There will be a processing workshop each day (any NMR software can be used, and we are grateful to Mnova for providing extra licenses). For more information and to sign up, visit http://nmrextra.chem.mcgill.ca/nmrisfun. Let me know if you have any questions.

We now have access to the QANUC 500! Details of signup are on the instrument page.  This is a very sensitive instrument for 1H 1D and 1H-observe 2D experiments like COSY, NOESY, 13C HSQC, and 13C HMBC.
