UPDATE ! AV300 : BACKUP BBO PROBE SHIMMED UP AND READY TO GO !
Dear All The ATMA probe has been sent for repairs and I immediately don’t know when it will return from the manufacturer. In the meanwhile, the Broad band BBO probe, which uses manual tuning/matching in place of the automated system is now in the magnet. Although we are all rather used to the comfort of […]

UPDATE ! AV300 – BACKUP MANUAL BBO PROBE IS GETTING READY
As I mentioned last week, the ATMA probe is now shipped to the maker for further repairs. The earlier BBO probe, where you tune/match by hand, is being shimmed up and getting ready for regular use. I estimate that the probe should be ready by the end of today. I will post another update announcing […]

UPDATE : DRX499 – SYSTEM IS BEHAVING (AGAIN !) NORMALLY
Dear DRX499 loyalists This time around, I think we have identified the operating system related issue and mitigated the same. The system used to freeze up within a minute or two earlier but it is looking and behaving normally for about 20 minutes now, and that is a positive sign. The Best way to see […]

UPDATE ! INSTRUMENT LOGBOOKS REVAMPED..
Dear Users This is a brief update on the topic of flaky Logbook behavior. Thanks to the immediate efforts of our department IT support, the Logbooks are back in action. Here is a quick link to the Logbooks that you can bookmark : https://depts.washington.edu/chemwp/chemwpnmr/equipment-logs/ What more, there are two additional features I want to highlight […]

UPDATE ! DRX499 – SYSTEM IS USABLE NOW..
Dear DRX499 patrons The computer system froze couple of times and we have done our part in reviving the same. As I write this, the spectrometer is usable as before but we will be closely watching the behavior, since we haven’t fully identified what caused the system freezes. So, if that happens again, feel free […]

ALERT ! AV300 – IMMINENT PROBE CHANGE
Dear Users Continuing on the ATMA probe, that underwent a substantial overhaul with considerable cost, we are convinced that the probe’s tuning/matching ability is not upto par with what is promised by this repair. You can realize this if you attempt to run ‘atma’ on solvents such as ‘C6D6’ and the system pretty much fails […]

ALERT ! NMR FACILITY SHUTDOWN DUE TO WATER EMERGENCY
Physical Plant is working on a water supply emergency that is confined to Bagley Hall. The building Administrator has ordered the NMR facility to be closed until further notice. So, you won’t be able to block NMR time until the situation returns to normal. I have tentatively blocked off the calendar to emphasize this point. […]

NOTE : INSTRUMENT LOGBOOK ISSUES
Hello NMR Users I recently learned of issues with posting messages in the instrument Log Books that is provided via a Web Page. It is a strange ‘Catch 22’ situation where you could not have communicated the problem via a Log Book entry ! While we are looking into solutions after simulating the problems at […]

UPDATE – AV300 : ABOUT THE ATMA PROBE
Dear User The probe has been fitted with a totally new Automatic Tuning and Matching hardware assembly as part of its refurbishment. This means that, when you run the ‘atma’ command and if the solvent that is used with your sample has not been already ‘registered’ in the probe’s database, it takes a while to […]
