Dear All,
Hope you all have great time.
One of our Varian GC MS saturn 2000 is not starting up. The software shows turbo speed reaching up to 64% and vacuum pump is in full speed. Anybody have any idea of why it is not pump down completely. Please advise.

thanks & regards,

Jihad

I have never used a Saturn but make sure you don't have a big leak. Plug the detector, clean, regrease and flip the o-ring between the manifold and turbopump and try to pump down again.
