The sample has been removed. The av300 system is working per usual.
Sample in 300 without sample holder.
ATMA doesn’t look right and it took a long time to complete. Topshim kept failing and I wasn’t able to get a spectrum.
Could not topshim of my sample, I tried 2 times. It signed that ” PrepareLock Lock is off”
Could not lock on my sample (in an appropriate amount of CD2Cl2). It didn’t look like anything was happening in the lock display. Tried several times and also tried locking on other solvents but same result each time. Sample locked fine on DRX499.
ATMA still a problem. Tuning lines were jagged and instrument did not find a match.
ATMA looks wonky instead of straight curved lines
ATMA problem — no error message given but no dip to be seen
1H tuning on the PABBI probe was acting up tonight. As the system is tuning/wobbing the signal has a bunch of random spikes and is doing all this weird stuff. It still tuned and gave me a decent spectrum, but I had restart the process a couple of times to get it to work.
Same as Brock:
When performing atma or atmm got the error message “channel cannot be set”
