48 Maintaining Your GC
4 Maintaining the Split/Splitless Inlet
To Change the Liner and O-Ring on the Split/Splitless Inlet
1 Gather the following:
• Replacement O-ring (See “Consumables and Parts for the
Split/Splitless Inlet” on page 36.)
• Replacement liner
• Tweezers
• Lint-free gloves
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.
If using a Flip-Top inlet, lift the lever arm.
4 Loosen the O-ring from the sealing surface with tweezers.
5 Grasp the liner with tweezers and pull it out.
6 Inspect the surface of the gold seal for graphite or rubber
septum contamination. If required, replace the gold seal.
(See “To Replace the Gold Seal on the Split/Splitless Inlet” on
page 50.)
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.
