To Change the Glass Liner on the Packed Column
Inlet
1 Gather the following:
• Replacement glass liner. See “Consumables and Parts for the Packed Column Inlet” on
page 96.
• 9/16-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 the inlet is hot, wear
heat-resistant gloves to protect your hands.
3 Loosen the top insert weldment to remove the top portion of the inlet.
4 Use a thin wire or wood splint to carefully lift and remove the old glass liner.
Wear clean, lint-free gloves to prevent contamination of parts with dirt and skin oils.
5 Wearing gloves, inspect the O-ring and replace, if necessary. See “To Change the O-Ring
on the Packed Column Inlet” on page 104.
