Replacing the Filament

Remove the old Filament and ion volume:
1. The ion volume on the enclosed source must be removed to
replace the filament. Use a hex wrench to remove the lock screw
on the collar which secures the ion volume to the source (see
Figure 4-1). Carefully remove the ion volume and set it aside.
2. Remove the six (6) ¼-28 bolts that secure the quadrupole head 10-
pin feedthrough to the vacuum system.
3. Remove and discard the copper gasket. DO NOT REUSE THE
GASKET.
4. Position the quadrupole head so that it is pointing up and is
secure.
5. The Filament plate is held in place by two (2) stainless steel rods
that carry the current to the Filament. Using the hex wrench
provided, loosen the two small set screws on the Barrel
Connectors that secure these rods in place, and slide the rods out
of the analyzer. Be sure to remove all residual pieces of the old
Filament.
