After trying to eject I got this error. Error: unable to connect to remote host (no route to host). The control/lock panel is also off which I assume is a related issue or the root cause. I was unable to eject the standard sample.
Not shimming properly with CDCl3 solvent. Peaks are washed out, broadened.
‘lockn’ command completes, but ‘topshim’ fails with the error ‘lock prior to shimming.’
Solvent lock won’t work on 301- could not run sample
On Monday, Nov 9 2021 at 2:10 pm, the solvent lock did not work for the AV 301 instrument.
Refused to lock CDCl3. Could not run.
Refused to lock onto solvent CDCl3. Re-locking, sample re-injection or re-running proton did not work.
During proton, output wobble signal too weak error. Re injection or using different samples did not work
* not my sample, but the spinner and dummy sample. Sorry!
Sample won’t eject and instrument produces an error.
