46 Maintaining Your GC
4 Maintaining the Split/Splitless Inlet
To Clean the Septum Seat in the Insert Assembly of the Split/Splitless Inlet
1 Gather the following:
• Replacement septum (See “Consumables and Parts for the
Split/Splitless Inlet” on page 36.)
• 0- or 00-grade steel wool (optional)
• Tweezers
• Compressed, filtered, dry air or nitrogen
2 Load the inlet maintenance method and wait for the GC to
become ready.
3 Unscrew the insert nut from the inlet body. Lift the septum
assembly straight up and away from the inlet to avoid
chipping or breaking the liner.
4 Remove the septum retainer nut or Merlin cap.
5 Use tweezers to remove the septum or Merlin Microseal from
the retainer nut. (See “To Change the Septum on the
Split/Splitless Inlet” on page 44.)
6 Scrub the residue from the retainer nut and septum holder
with a small piece of rolled-up steel wool and tweezers. Do
not do this over the inlet.
WARNING
Be careful! The oven and/or inlet may be hot enough to cause
burns. If either is hot, wear heat-resistant gloves to protect your
hands.
