Agilent 5973N signal loss
Good Evening !
Well, not so good here... I am stuck with an EMERGENCY trying to figure out why my MS just stopped working.
Was running a basic DFTPP, Cal Check to start a run batch and when I returned the samples had been running and stopped collecting any data... just a bunch of noise. Thinking went to manual tune and chenged my filiment thinking I might have an issue there... same issue. I vented the system and checked my source and it was relatively clean and the filiments were intact. I chenged the filiments just to be safe and put everything back together.
I ran a manual tune and I am get basic scans, but the repellervoltage keeps fluxuating.. I m going to replace the Repeller insulator and check all of the connecting but I am thinking I have a bigger issue here. This instrument went from working very well non-operational.
I an't think of anything else off the top of my head unless there is an issue with the EM... The source is in great shape. My other instrument is down and I have been to swamped to even go through the suggestions posted.
Help !
