Though I haven’t heard of specific reports, all the NMR consoles in Rm:37 evidently underwent some voltage fluctuation, possibly anytime over the weekend. All the log posts of today morning are related to this.  The systems have been reset to their usable condition now. NMR Facility Manager 9/18/2017

I have checked that the locking on CDCl3 as well as other solvents is functioning as expected. Nevertheless, do post a message in the log if you notice otherwise, especially with non-standard solvents. NMR Facility Manager 9/6/17

The apparent Lock anomaly noted with AV300 has also been found with AV301 and possibly DRX499.  Apparent line voltage fluctuations were reported today and similar to last week, that could be cause of the Lock disruption.  The 300-s are restored to normal operation as we speak and I am checking that DRX499 is functioning as […]

Reservation calendar is released for AV500 also.  The charges for unused time during the window of instrument revival, will be waived for all users who might have made reservations earlier. NMR Facility Manager 8/31/17

Following consoles are up and running : AV300 AV301 DRX499 I will post further update once AV500 is on line. NOTE :  During the process of revival, there were voltage fluctuations several times today.  Until this issue is fully resolved campus wide, it is possible that the systems may fail to operate once again, in the […]

None of the instruments in Rm:37 are usable as we speak, due to a power interruption that occurred today morning around 9 am approx.  I will post a follow up message once all the instruments are revived. Until that time the reservation calendar will be disabled for fresh bookings. NMR Facility Manager 8/31/2017

Fragile Quartz insert tube inside the probe is found to be broken and that is the cause of the lineshape anomalies users have noticed recently.   We will replace the broken part as soon as feasible, shim up the probe again and release it for use.  Currently I don’t have an estimate but I will provide […]

Currently, we don’t have an estimate as to when the original ATMA probe will be fixed and ready but I suspect it will be at least a week.  Updates will follow at relevant points. NMR Facility Manager 7/12/17

As we announced a week earlier, the ATMA probe is pulled out for servicing the dysfunctional X-channel.  The backup BBI probe is being shimmed up and getting ready and we hope that it will be available by the end of the day. Two important points :   This legacy probe DOES NOT HAVE ATMA ! […]
