Maintaining Your GC 57
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 42.
• Replacement washer
• 1/4-inch wrench (for column)
• 1/2-inch wrench
• Lint-free gloves
2 Launch the GC maintenance wizard: Maintenance > Inlets, select the inlet, then select
Perform Maintenance > Replace Gold Seal (bottom) > Start Maintenance. The wizard will
walk through the steps needed to replace the liner and O-ring (those same steps are
repeated below). 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.
