some garbage
Some peaks on the spectrum were upside down.
Topshim failed repeatedly – field map error
When tunning and matching, the match could never get low enough to meet the baseline – and was considerably high up
Locked the sample repeatedly, lock line in the little window looked noisy
Had to rewobb 3 times and still did not work
Spun rate read error prevented operation of software
Will not shim with topshim (sometimes it works after the 5th attempt). Today it would not shim even after repeated topshim runs. (solvent was CDCl3).
WOnt topshim
I could not use the AV500. I got a pop up window saying “Spin rate read error” when I logged in. I could not eject the sample or enter any other commands
Data comes out unusable. Topshim maybe working? Not any obvious errors but multiple fails between different samples. Running in DMSO (temp fine)
