400 MHz QNP Spectrometer - 'Lagavulin' - Room B25
The 400 MHz spectrometer in B25 is one of our open access walk-up instruments. It has a QNP probe which can observe 1H, and switchable 13C, 19F and 31P - the switching is automatically carried out using a pneumatic system. The spectrometer is controlled by a bespoke Glaxo Smith Kline program, and submission of samples takes place on the separate computer. The experiments that this spectrometer will run are:
1H-PDF - Standard Proton experiment without printout, PDF only - Daytime
1H - Standard Proton experiment - Daytime
19F - Standard Fluorine experiment - Daytime
Interpretation Aid - 1H and COSY experiments - Daytime
Quick 13C - Standard Carbon experiment - Daytime
Quick 31P - Standard Phosphorus experiment - Daytime
1H, 13C, 31P Overnight - Proton, Carbon and Phosphorus experiments - Overnight
1H Overnight - Longer Proton experiment - Overnight
All data will be emailed to you if you type your email address into the comments box, regardless of experiment chosen.
The experiments are queued in order of submission for daytime and overnight experiments and the machine automatically works through the list in turn. Daytime experiments will run overnight if there is spare time. The overnight period runs from Midnight to 8am which offers late-workers the chance to get one of the quick daytime experiments run before they leave for the night.
When submitting samples to the instrument would all users please stick to the following convention:
Group Code followed by /, then your personal identifying code. For example DRS/ABC25_100_Fr1 or SB/BRS1-35-2
By following these rules it makes things much easier when preparing the usage lists at the end of each month.
You can view the samples waiting and the samples done by accessing the auto-updating web pages through the backup server Scapa.
Navigate to \\scapa\NMRshares\lagavulin-queue
Every hour the system sorts zipped data into a folder on the backup server according to your group code. This can be found at \\scapa.ch.cam.ac.uk\NMRarchives\zips
Please remember to collect your tubes promptly after they have been run. Tubes left in the room are cleared every Tuesday morning around 9am and can be found in the labelled beaker in the fume hood in B28.
