As I was taking NMR sample out, green substance on NMR tube.
Also, there is a strange smell all around the NMR instrument.
Could not atma on proton experiment – was stuck on the screen where it was trying to find the minimum point on the curve.
When running atma, the process starts, and then after a few seconds I get the following error message in a popup box titled wobb:
“Error in ipsoControl::checkStatus(): Status line active!”
When I close out of this popup box, it appears again, then after closing out the second time I get another error message popup:
“Error in Master: Error 13 in AQS1: –SLOT 1 RACK 1: power failed”
Closing out of that, I get the error popup:
“Error: can’t stop wobb process”
when I typed rga, got the following message: “DRU1 does not support digitizer ‘HADC’ defined in the current data set! Change the digitizer of the current data set to continue”
The gas flow is low and is giving error messages.
My sample is stuck in the 700. I injected it and it showed that it went down but I was having trouble locking onto signal so I tried to eject but it got stuck somehow.
In CD2Cl2 and THF d8, it is unclear if I am actually locking (though it says that lock was completed and I can see the signals in the lock display). Also, when topshim is attempted, it says “RawCheck – no signal at all”. No spectrum can be obtained
In methylene chloride and THF, it is unclear if I am actually locking onto a signal (though it says lock completed and I can see the signals on the lock display). When shimming is attempted, it says “RawCheck – no signal at all”
I am not able to lock any sample, or find the lock signal on 10% D2O or the 50/50 dummy sample.
The XServer is working now again
