The VTU was set to 45 C when I used the spectrometer at 4:00 PM today (7/2). If you change the temperature for your experiment, please remember to change it back to 25 C as a courtesy to other users. Thank you!
The 1H match rod will not turn one way or the other. Am afraid to apply too much pressure for fear I’ll break it.
Topshim failed, “FieldMap — Signal to noise too low.
Spin rate error, dummy sample would not eject.
TopShim failed, with error message, “FieldMap — Signal to noise too low.” Works for some samples, not for others. I have not changed my sample depth or concentration lately, so this baffles me.
spin rate error.. dummy sample can’t be ejected!
Dummy sample will not eject. Error message “spin rate read error.” Spinner broken?
