Monday - November 16, 2009Bruker BACS problems (updated)After just under 12,000 samples, the Bruker sample changer (BACS) is having problems. Thursday - November 05, 2009Bruker 400 (updated)The departmental Bruker AvanceIII-400 has some problems. First, Fluorine-19 tuning has become unreliable. Second, shimming also has become unreliable. Bruker personnel installed patches to tuning and shimming and these are working again. Thursday - November 05, 2009Staffing updates November 2009 (updated)Just a note on staffing. First, Dr Timothy Burrow has the flu and pneumonia and will not be back to work until Monday November 16th. Second, Ms Rose Balazs is on medical leave until mid-November. At this time only Dr Golembek is available and she will be in with her usual hours; 8:30-3 Monday, Tuesday and Thursday. Friday - October 30, 2009TuningSome users are confused over tuning and what it does. Some probes appear not to need tuning whereas the newer systems spend some time tuning. Friday - October 30, 2009Varian VnmrS-400 spinning issuesThe inside of the magnet (what we call the upper barrel) was dirty and samples did not spin. This has been fixed. Friday - October 30, 2009Bruker issues on overnight samplesThere was an error running samples overnight last night, for samples submitted on October 29. Wednesday - October 28, 2009MestreNova on Keroppi upgradedI've upgraded the copy of MestreNova on Keroppi to version 6.0.2, the latest version. Version 6 has some nice additions that would be useful for all chemists, see below (Images stolen from MestreNova LLC): Tuesday - October 27, 2009Bruker Avance IssuesTHere has been an intermittent error on the Bruker Avance III while running samples overnight. Many samples were not run. Last night, several samples were left in the queue, and not run. Friday - October 23, 2009Varian Mercury 400 issuesThe spinning rate control on the Varian Mercury 400 was not functioning correctly. A sticky valve was replaced and spinning is working again.

Tuesday - October 06, 2009Manager away until October 19thDr Timothy Burrow will be away until October 19th. Dr Adina Golombek will be in as usual, on Mondays, Tuesdays and Thursday until 3PM. Ms Rose Balazs is away until October 12. Dmitry will reset the sample queues in the morning. Tuesday - September 22, 2009Varian Mercury 300 issuesThere have been some problems with the Mercury 300: On Friday, September 18, a brass hose connector came loose, causing incomplete ejection of samples and some broken NMR tubes. Today, we spent some time looking over the spectrometer. I found a loose solder connection on the proton pre-amplifier. This will be fixed in-house. Wednesday - September 16, 2009Mercury files not transferredThe server was patched and rebooted yesterday Sept 15 2009. For about 4 hours (10 AM to 2 PM) FIDs were not transferred. Wednesday - September 16, 2009Monday - September 14, 2009Helium fillsWe will be doing helium fills on the following spectrometers: Mercury 200, Mercury 300/SMS, Mercury 400/SMS, Unity 500 and Avance 400/BACS starting tomorrow, September 15 2009! Friday - September 11, 2009Bruker Avance III-400 P31 shift errorAll Phosphorus-31 chemical shifts of samples run in C6D6 have an error! The chemical shifts are shifted downfield by 13.3560 ppm. Wednesday - September 09, 2009More server fall-outSome problems with moving to backup hardware after the server failed. FTP was not working Printing to "babe" was not working Mail out of NMR was not working until this morning. Update September 10/2009 11 AM. The departmental proxy "grandial" was being blocked. Only windows users within the department were affected and could not access the booking schedule and training signup. This has been fixed. Files from the Mercury 300 and 400 were not being copied for ~24h, an errant space in the script was removed and files are being copied again. Update September 10/2009 1 PM. Bruker files now transferring! Tuesday - September 08, 2009Server problemsBecause the Data drive (where all user data is stored) was reaching capacity, I copied all data to a new RAID system and installed in the server. All the data is OK, but the system did not boot. [6:15 PM most systems are now back online. The server had major hardware problems] [7:15 PM all spectrometers working, all data stations working] Tuesday - September 01, 2009Plotting colour issuesThere are problems with colour plotting from Keroppi. Follow these instructions to get the colours you want. Monday - August 31, 2009Keroppi finally fixedThe workstation Keroppi is working again. It has a copy of MNova and VnmrJ for users to process NMR data. Monday - August 31, 2009NMR server problemsThe boot hard drive on the NMR server had problems starting ~9PM Saturday August 29. The drive was fixed by 11:45 PM. Saturday - August 29, 2009Mercury 400 problemsCommunication between the console CPU and the Sun Sparcstation was lost last night ~ 9 PM. A faulty ethernet cable was replaced and the system is working again, 3 PM Saturday August 29. Tuesday - August 25, 2009Connection to "nmrweb" blockedPeople within chemistry cannot connect to the nMR booking server, https://nmrweb.chem.utoronto.ca/ This is because of a configuration of the departmental squid proxy (grandial). Tuesday - August 25, 2009Mercury 400 problemsThe old software/sun computer system have had some problems lately. Monday - August 24, 2009Swap of AutoX probe on Varian VnmrS-400There is a problem with the tube switch selector on the probe in the Varian 400; the probe will be sent for repairs. We plan to swap the probe on Thursday August 27th, thus the spectrometer will be unavailable that day. Monday - August 24, 2009Thursday - August 20, 2009Monday - August 17, 2009Mercury 400 spinning issues [solved]There is a problem with the spinner control on the Varian Mercury 400. The part is is only about 25 years old... Thursday - August 13, 2009Bruker AVIII-400 with BACS working againAccording to the schedule, the Bruker AVIII-400 with BACS was checked. Also, not according to schedule, a leaking condensation pump in a room across the hall flooded the floor around the system with dirty water. Wednesday - August 12, 2009Workstation Keroppi problemsThe workstation keroppi suffered a hard drive failure. Wednesday - August 12, 2009NMR server blockedAfter a misconfiguration, the NMR server timothy was blocked by Frank Bures. We are waiting for it to be unblocked. [AT 4 PM, the server was unblocked] Tuesday - August 11, 2009Mercury 400 issues resolvedThis morning, a tube that was cracked on the bottom was found on the sample changer rack of the Mercury 400 this morning. Because it was unclear if the crack was there before or after the sample was run, as a precautionary measure, the probe and upper barrel were washed and cleaned. Tuesday - August 11, 2009Server updatesThe main NMR server will be updated today for security patches, with reboot around 10 AM. [Update: server rebooted and all services restored.] Thursday - August 06, 2009Thursday - August 06, 2009Carbon with Fluorine decouplingCarbon spectra with fluorine decoupling has been added to the VnmrS-400. This used garp decoupling to decouple from -100 to -175 ppm (the usual organic range). To change the decoupling window, set the "dof" parameter appropriately. Click on the CarbonDECFluorine button on the experiment tab. There is also Phosphorus and Boron with Fluorine decoupling, which are PhosphorusDECFluorine and BoronDECFluorine, respectively. Note that since the probe is only two channel, there is no proton decoupling; we need a H/F/X triple probe to decouple both proton and fluorine. Tuesday - July 21, 2009Work on Mercury 300There will be no access to the Mercury 300 on July 29 and July 30 for routine maintenance and computer upgrade. Tuesday - July 21, 2009Helium Fills July 27, 2009Access to the Mercury 200, Unity 400 and Unity 500 will be limited on Monday July 27, 2009 for LHe fills.
