Maintaining the Purged Packed Inlet 6
Maintaining Your GC 79
To Clean the Septum Seat in the Purged Packed Inlet
1 Gather the following:
• Replacement septum (See “Consumables and Parts for
the Purged Packed Inlet” on page 68.)
• Septum nut wrench
• 0- or 00- grade steel wool (optional)
• Tweezers
• Compressed, filtered, dry air or nitrogen
• Ultrasonic cleaning bath
• Lint- free gloves
2 Load the inlet maintenance method and wait for the GC
to become ready.
3 Remove the septum retainer nut or Merlin cap.
4 Loosen the top insert weldment and remove.
5 Use tweezers to remove the septum or Merlin Microseal
from the top insert weldment. Do not gouge or scratch
the interior of the septum head.
6 Scrub the residue from the top insert weldment and
septum nut with a small piece of rolled- up steel wool and
tweezers. Ultrasonically clean the retainer nut and top
insert weldment.
7 Use compressed air or nitrogen to blow away the pieces
of steel wool and septum.
8 Wearing gloves, inspect the O- ring and replace, if
necessary. (See “To Change the O- Ring on the Purged
Packed Inlet” on page 83.)
9 Install the top insert weldment and hand- tighten firmly.
Be careful! The oven and/or inlet may be hot enough to cause
burns. If the inlet is hot, wear heat-resistant gloves to protect your
hands.
Wear clean, lint-free gloves to prevent contamination of parts with
dirt and skin oils.
