UPDATE ! 500 NMR-s WORKING OK
Dear Users Most probably, there was a power fluctuation in the past day or so that led the 500 NMRs into an unusable state. The situation is remedied and everything looks normal with these instruments. In case you are curious, the 300-s have been behaving OK when I checked this morning. NMR Facility Manager 5/31/2022

UPDATE ! AV300 – ATMA NOISE ISSUE IS ADDRESSED
Dear Users Some of you had notified us that the V-shaped ‘wobb’ curve was showing lot of noise and ATMA was having issues in tuning/matching automatically. The problem was identified to be localized only to the 1H channel and subsequently, the cause for this has been addressed. My tests today show that the system is […]

As I write this, the system is in a normal state and I have recalibrated the sample spinning system and tested it. Locking per se works fine but I have to see if specific solvents are […]

UPDATE – AV500 ! TXO-1H {13C,19F} PROBE IS BACK
Dear Users As we suspected, a mechanical issue was the cause of 13C channel’s failure. We could fix this in-house with the happy ending that 13C Tune and Match behave pretty smooth now. The TXO probe is back in the magnet, ready to collect data. NMR Facility Manager 12/7/21

ALERT ! AV500 – POSSIBLE PROBE SWAP TODAY ON THE CARDS
Dear Users The TXO probe has been needing some attention vis-a-vis the 13C channel. As I speak, we are looking into it. If it’s a quick fix in-house, the same probe will go back in the instrument. If not, I will have to place the BBO probe in its place. Sorry for this last minute […]
