swap the filament on Agilent GCMS

[sepscientologist]

I remember that there are two filaments installed. How do I switch them?

On the tune page, one of the parameters in the upper left part of the parameters box, you can change the filament.
Sorry--a bit incoherent, since I'm in my office and not at my instrument.

If it's a 5970 there is a toggle switch at the rear of the analyzer assembly.

Got it. Switch to 'tune' view. Choose 'manual tune'. There you can see which filament is active and switch.
