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, […]
