To Install a Capillary Column with the
Programmable Temperature Vaporization Inlet
1 Gather the following, see “Consumables and Parts for the Programmable Temperature
Vaporization Inlet” on page 144:
• Column
• Graphpak 2M ferrule
• Column nut
• Column cutter
• Septum
• Isopropanol
• Lab tissue
• Metric ruler
• 5-mm and 6-mm wrenches
• Typewriter correction fluid or a marker
• 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.
Wear safety glasses to protect your eyes from flying particles while handling, cutting, or
installing glass or fused silica capillary columns. Use care in handling these columns to
prevent puncture wounds.
3 Before installing the column, install the correct column adapter. See “To Replace the Inlet
Adapter for the PTV Inlet” on page 158.
Wear clean, lint-free gloves to prevent contamination of parts with dirt and skin oils.
4 Place the column on the hanger with the ends pointing up and the label to the front.
5 Place a Graphpak 2M ferrule onto the column, with the graphite facing up towards the inlet.
6 Score the column using a glass scribing tool. The score must be square to ensure a clean
break.
