Hi guys, I've got a 5975 that was vented for around 2 months due to the whole helium thing. The analyzer chamber was sitting at ambient for the duration, multiplier was still pretty new so I did some maintenance and pumped it down to try and save what was left of it. I tuned it 2 days later and I'm seeing a huge nitrogen peak. 69 is at ~620k counts and 28 is around 7.5 million, I don't think the turbo would even spool if it was this bad of a leak. I sprayed the door and mass spec inlet with duster and didn't see a spike on mass 51. Vacuum is reading 7.12e-6, does it just need more time to pump down since it was vented for so long or am I missing something here?
Thanks,
