AV700 and DRX499 UPDATE : PLEASE READ – SOLUTIONS TO SOLIDS TRANSITION – PLANS

The AV700 NMR spectrometer will be receiving a new Solid State MAS NMR probehead within the next few weeks.  I will announce the finer details of this piece of equipment later. Please note that, currently the instrument is transitioned to solid state NMR mode to confirm its functionality before the new probehead is installed and […]

ANOTHER UPDATE ! AV500 : TOPSHIM IS STILL NOT RELIABLE

I apologize for jumping the gun and announcing that Topshim is working ok.  The latest I checked with a CDCl3 sample, I had poor signal to noise issues which I need to investigate further. Alas, for the present the shimming has to be done by hand, I am afraid.  But, I am planning to tackle […]

UPDATE ! AV500 – TOPSHIM FUNCTIONALITY IS BACK

You can use the Topshim shimming routine on all deutero solvents as before.  We will keep a close eye to see if anything is compromised again but, tests thus far indicate that the functionality is back on track. Please post a message in the log as soon as you notice something amiss and thanks. NMR […]

ALERT ! AV300 : X – CHANNEL MALFUNCTION

The X-channel i.e. 13C and 31P, etc. is not functional.  We have identified the most probable cause to be a faulty circuit board but it’s fix may take some time. Most probably a replacement unit will need to be obtained and that might take a few days. Since the 1H is the predominantly used nucleus […]

UPDATE ! DRX499 – CURRENT STATUS

Since there is still quite a few loose ends to tie up before the merged 500 MHz console is declared open,  the existing DRX499 is back in operation as before. After this note, I will proceed directly to introduce the merged console to you, once it is confirmed to be functional in every respect. Thank […]

PLEASE READ ! DRX499 – IN REINCARNATED FORM

Many of you might have noticed an anteroom on the right, when you enter the NMR lab Room : 37 (it has a room number : 33, Bagley Hall).  The more inquisitive among you might also have seen an NMR instrument in that space.  This instrument originally belongs to Prof. Gabriele Varani of our department […]

ATTENTION USERS ! – SPECIALIZED TRAINING PLANS – PLEASE READ !

Over and above the simple but minimal training that is provided by the facility for the new users,  we always recognized the need for training you in some special tasks such as how to properly maneuver the Lock facility or how to Shim by hand when Topshim fails, to site as examples. We are finally […]

UPDATE : AV300 – PROGRESS WITH UDRIVE MIGRATION – BUT NOT READY YET

A few more lose ends to tie up before you will be ready to access the UDRIVE, similar to AV301.  But the needed work will be done remotely without disrupting the regular use of the spectrometer. I will post another heads up message when we say it’s ready.  In the interim, your data collection protocol […]

ALERT ! AV300 – UDRIVE UPGRADE SCHEDULED FOR TOMORROW

The Operating System and associated components will be upgraded starting tomorrow morning 9 am i.e. Tuesday, 31st of July ’18.  Assuming that everything goes well, the interface you will see from 12 noon will be similar to the one on AV301.  Also note that the data from then on will be directly written into your […]
