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 […]

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 […]

NOTE ON AV301 – PABBI PROBEHEAD AND SHIM
As already mentioned, the new gradient upgrade is designed to function with only the ATMA-BBI probe, as currently there are no other 300 MHz probes that feature gradient capability. So, the probehead has been changed to PABBI and the probe ID card on the console lists the shim file to load and use along with the […]
