AV300 – UPDATE ! DATA STORAGE PARTITION IS MOVED
If users recall, we place special emphasis on the fact that you should download your datasets then and there and don’t leave it on the NMR computer. A good validation of that occurred yesterday as I found that the external hard drive storing NMR data crashed with mechanical failure. As a result, you won’t see […]

ALERT ! AV300 – SYSTEM IS READY FOR USE
With a new part replacing the faulty hardware, the spectrometer is tested and ready to go. Users can start reserving time as usual. Adrienne or myself will follow up on tweaking a few of the pulse parameters later but the default values you get with ‘getprosol‘ command should be good for routine use. Please keep […]

AV300 – UPDATE : WAITING FOR BROKEN HARDWARE COMPONENT
We had identified the faulty circuit board, that led to the ‘wobb’ problem and most probably compromised parameters in a regular NMR measurements, that were not noticed by many. While waiting for a replacement from manufacturer, we are putting every effort to fix this in house, if we can. We estimate that it will be […]

The BBI Z-gradient probe has been repaired and is ready to be installed and field tested. We will put in the probe by the afternoon of Thursday, 11th February ’16. Hoping that everything turns out right, the spectrometer should be ready for regular use by that evening.

UPDATE – AV300 : HARDWARE ISSUES IDENTIFIED AND AV301 IS WELL AND HEALTHY
First of, my sincere ‘thank you’ for putting up with the erratic schedule on the AV301 calendar yesterday, while we were trying to troubleshoot the tuning/matching problem on AV300. I am sorry that I could not prepare the user base more in advance for this interruption. As you all seem to know, AV301 has been […]

AV301 ALERT! – USER TIME
While the av300 tune and match issue on the wobble curve is being addressed, there may be short notice cancellation of user’s time on the av301 to aid in the av300 repair. Please check your time on the av301 at the last minute to be sure the Facility has not over-ridden it. The NMR Facility […]

UPDATE – AV300 – SYSTEM WILL BE DOWN UNTIL FURTHER NOTICE
The preamplifier module is out of action for component level troubleshooting in relation to the tuning and matching issue. There is no easy workaround at this point to keep the spectrometer running and so users are requested to engage other instruments for routine spectroscopy. Updates will be posted as soon as we make progress.
