UW CHEMISTRY NMR

The av500 is now available with the TXO probe. This probe has 1H, 19F, and 13C capabilities with proton decoupling. It is a 5 mm probe, the same TXO you have used on the av500 in the past. Topshim is available on this console with this probe. Follow the instructions posted next to the workstation. […]

Until the user’s sample stuck inside the room tempearture bore of the magnet is removed, the instrument cannot be used.  Please wait for an update after the clean up to complete, before attempting to use the machine again.

All the normal functionalities including atma are restored to their original state.  Users are requested to use the atma command for automatic tuning and matching of the probe.  The optional atmm command is also available, if you so prefer.

Some of the users complained that the ATMA takes unduly long time to finish.  Part of the problem is the large default sweep width used in the user’s dataset, which makes the ATMA command to search long for a solution.  If you encounter this, please do the following : Stop the WOBB by pressing the […]

Please use the reservation system per usual for all time after 10:45 am.

We are aware the instrument reservation online system is down. It is currently being worked on. Until the reservation system is up, you can reserve your NMR time by using the sign-up sheet next to the NMR instrument you want to use.

The AV301 now has the dual channel probe with 1H and 13C and a 2D lock. Please use shim file stdhcd. The proton and carbon macros are not currently set up to reflect the new probe. You will need to tune and match this probe for your experiments.

Please remove any samples in the magnets before the consoles are powered down.  The instruments will be back to normal operation approximately by 6.00 pm tomorrow.

The air supply has been restored, and the NMRs are ready for use.  

Due to the unannounced utility shutdown the NMR facility is now closed until further notice.  I have been told the air supply will be back up sometime between 11am and 3pm.  I will post when the air supply has returned and the facility is back in working order.
