REMINDER : NEO500 – CALENDAR AND QUEUE
Dear Users We hope that you have come to like the convenience of walking up to NEO500 without planning to reserve NMR time a priori. This is a decidedly efficient protocol in extracting maximum from the instrument as well. Nevertheless, ensuring the smooth running of this complex system that can always give you the data […]

SNAP POLL: GG500’s NEW BBFO iProbe – SOLICITING YOUR INPUT
Dear Users Just short of two months ago, I made an announcement about GG500 getting its own brand new fully automated BBFO probehead. Click on this link to that post, for quick reference. We ran into some technical challenges in integrating that probe with GG500, but they have been sorted out. The probe is ready […]

REMINDER ! PLEASE RESERVE YOUR NMR TIME FOR GG500 AND 300 INSTRUMENTS !
Dear Users While we are very happy to see that you are all getting comfortable with the truely ‘walk-on’ nature of running NMR with our new NEO500 system, unfortunately, this process cannot yet be replicated on the other instruments. Until we get a fully automated setup with multiple sample handling on the other instruments, YOU […]

NEO500 : IMPORTANT CLARIFICATION ABOUT TUBE LENGTHS
Dear Users While you were trained on the new NEO500 system, you were told that it is OK to use the J-Young type tubes even with this fully automated system. This is definitely true, but certainly there is a caveat to that statement. Please look at the picture below. The ‘dotted line’ is roughly the […]

UPDATE ! AV301 : TOPSHIM TEST LOOKS GOOD
Dear Users I managed to get hold of six sample tubes of same compound in CDCl3, (thanks to the kind help from Chem Lab Techs, David and Lance) to test the Topshim consistency. In my experience, the shimming is consistent and reliable. Below is a snapshot of the aliphatic region from all the six samples […]

UPDATE ! AV300 – SYSTEM BACK IN ACTION…WITH THE ATMA PROBE !
Dear Users Despite my ominous message earlier about putting a backup probe in place with manual operations, I am glad to report that we managed to fix not only the ATMA probe in-house but also the original issue in the console electronics, which drove this venerable Probehead crazy. I have released the instrument for regular […]

ALERT ! AV300 – SYSTEM DOWN DUE TO PROBE ISSUES
The ATMA Probe is repeatedly failing in both tuning/matching and gradient shimming parts. Though we will first attempt to find an in-house remedy for the above, the chances are slim that it will be successful, given the history of this probe. We will do what we can to provide a backup probe in the system, […]
