To Replace the Gold Seal on the Split/Splitless Inlet
1 Gather the following:
• Replacement gold seal, see “Consumables and Parts for the Split/Splitless Inlet” on
page 50.
• Replacement washer
• 1/4-inch wrench (for column)
• 1/2-inch wrench
• Lint-free gloves
2 Place GC in maintenance mode: Maintenance > Instrument > Perform Maintenance >
Maintenance Mode > Start Maintenance. Wait for the GC to become ready.
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.
3 Remove the inlet liner.
4 Remove the column from the inlet. Cap the open end of the column to prevent
contamination. Remove the insulation cup around the base of the inlet.
5 Loosen and remove the reducing nut. Remove the washer and seal inside the reducing nut.
Wear clean, lint-free gloves to prevent contamination of parts with dirt and skin oils.
