UPDATE : AV300 RETURNED TO USE
After attending to the tune issue on the probe that is directly caused by users using fingers to turn the turn rods, push past the stop point of the tune rod, or using the tune tool incorrectly, the av300 BBI probe has been repaired and is returned for use. The NMR Facility cannot stress enough […]

ALERT: AV300 UNABLE TO RUN DUE TO TUNE ISSUES
Users: The av300 BBI probe has been misused again and is no longer tuning/matching on the 1H, which precludes proton and any 1H-decoupled-X-observe NMR. Until the NMR Managers can take a look, please do not run on the av300 because using the av300 in its current state risks further damage to the console. Please watch […]

ATTENTION ! AV301 UPDATE : GRADIENTS AND TOPSHIM OPERATIONAL
The new gradient capability is fully functional. Combined with the ATMA feature of the porbehead, users can do everything from the computer desktop, including shimming using TOPSHIM. PROBE TUNING : After inserting sample and setting up the correct dataset, just enter atma on the command line. Wait for the auto tuning/matching to complete. SHIMMING : Topshim […]

UPDATE ! AV301 – SYSTEM IS READY FOR REGULAR USE – GRADIENT UPGRADE INCOMPLETE
I apologize for this unexpected delay in implementing gradient upgrade but we hope the wait will be worth it, once users can let the computer do all the shimming. I am glad to report that the major part of this hardware and software upgrade is done and I hope that by Thursday, the 12th, […]

AV300: 1H Tune Issue
The av300 is currently down due to an issue with the probe that occurs when users use fingers to tune or use the tune tool at an angle on the 1H tune rod. We are currently working to fix the probe and will notify users when the instrument is available again.

NOTE ON AV301 – PABBI PROBEHEAD AND SHIM
As already mentioned, the new gradient upgrade is designed to function with only the ATMA-BBI probe, as currently there are no other 300 MHz probes that feature gradient capability. So, the probehead has been changed to PABBI and the probe ID card on the console lists the shim file to load and use along with the […]

AV301 – UPDATE : GRADIENT UPGRADE
The hardware installation is complete but there are few more configuration steps that involves the software. I hope that this can be completed by tomorrow, unless some issue crops up in the meanwhile. I will keep you posted. NMR Facility Manager 11/3/15

ATTENTION – AV301 USERS ! – HARDWARE UPGRADE – GRADIENT CAPABILITY IS COMING TO AV301
We are excited to announce that the AV301 instrument will get new hardware upgrade that will make it the third instrument in Bagley 37 to perform gradient assisted spectroscopy. In combination with the ATMA-BBI probe, this will become a fully automated spectrometer for routine spectroscopy. Other than injecting the sample, every other operation can be done from […]

UPDATE – DRX499 – INSTRUMENT RELEASED FOR USE WITH TXO PROBE
The BBO probe has been found to have multiple hardware issues which are being addressed. To get to back to productive runs, we have placed the earlier TXO – 19F,13C {1H} – Z gradient probe for regular use. I would like to point out that the non-spinning shims are not upto the best spec but […]
