Greetings all,
I am the caretaker for a lone Bruker AC300 NMR. I filled it with liquid Helium this morning and the fill appeared to go fine. It was just like the previous 2 fills that I have done with this system. However, this is my question, the Helium percent level that the console gives as a number has not changed from the pre-fill value. Should I be concerned about this? My previous system often gave false numbers to me, but it was a QE 300 system and not a Bruker system.
This could be related, but our campus has been experiencing some power issues that do not seem to be affecting the NMR at this time. I have not noticed any problems with the system. This appears to be the only quirk with the system that I have noticed in the 1.5 years I have been watching over it.
Any comments are appreciated,
Thank you,
