50 Maintaining Your GC
4 Maintaining the Split/Splitless Inlet
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 36.)
• Replacement washer
• 1/4-inch wrench (for column)
• 1/2-inch wrench
• Lint-free gloves
2 Load the inlet maintenance method and wait for the GC to
become ready.
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.
6 Put on gloves to protect the new gold seal and washer from
contamination. Put a new washer in the reducing nut and
place the new gold seal on top of it (raised portion facing
down).
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.
CAUTION
Wear clean, lint-free gloves to prevent contamination of parts with
dirt and skin oils.
