To Condition a Capillary Column
1 Gather the following:
• One 7/16-inch, and 1/4-inch wrenches
• No-hole ferrule. See “Consumables and Parts for Columns” on page 30.
• Column nut
Do not use hydrogen as the carrier for conditioning! It could vent into the oven and present an
explosion hazard.
2 Manually set the inlet and oven temperature to < 40 °C, and wait for the inlet, oven, and
other parts you might come into contact with inside the oven, to cool before continuing.
Alternately, place the GC in maintenance mode: Maintenance > Instrument > Perform
Maintenance > Maintenance Mode > Start Maintenance.
Be careful! The oven may be hot enough to cause burns. If the oven 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 Install the column into the inlet using the new ferrules.
