I'm having some difficulty troubleshooting an issue I'm having with our mass spec 6120B model G7111B. Intermittently I receive an error for "octopole RF voltage could not be maintained" and the mass spec shuts down mid-run. I then shutdown the computer and reboot and the mass spec runs fine after that. I called the service line and they said it could be 1 of 4 issues, either the octopole itself is bad, voltage on the PCA board is off and they suggested "dipping" the instrument, or either the PCA or main board is bad. I was getting this error last year and plugged the octopole assembly out and cleaned it and did not have an issue for 4-5 months until recently when it flagged the same error code. Any suggestions that could be implemented internally would be great.
