what a routine PM for gcms includes?

just bought a PM from a third party vendor, want to make sure that they complete the whole list of PM?

Normally I would think for the MS would be cleaning the source, changing the rough pump oil, changing the diffusion pump oil if so equipped, new filaments, and initial pump down with leak check and tuning. GC would be inlet maintenance and leak checking. A final injection to verify sensitivity may also be included.
