To Install a Packed Column Adapter on a Detector
Fitting
This procedure applies to the FID, FPD+, NPD, and TCD.
1 Gather the following:
• Packed column adapter, see “Consumables and Parts for the Packed Column Inlet” on
page 96.
• Ferrule, Vespel/graphite, 0.8-mm id
• 7/16-inch wrench (for the packed column adapter and 1/8-inch packed column nuts)
• 9/16-inch wrench (for 1/4-inch packed column nuts)
• 1/8-inch nut and ferrule for a 1/8-inch packed column, or a 1/4-inch nut and ferrule for a
1/4-inch packed column
• 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 detector may be hot enough to cause burns. If the detector is
hot, wear gloves to protect your hands.
Wear clean, lint-free gloves to prevent contamination of parts with dirt and skin oils.
Handle the adapter carefully and install the packed column before installing the adapter into
the detector base. The thin-walled capillary tube that carries the sample into the detector can
be damaged by rough handling.
3 Place a ferrule onto the packed column adapter.
4 Carefully install the adapter assembly into the detector fitting. Align the adapter so the it
enters the detector fitting as vertically as possible. Avoid stressing the adapter capillary
tube. Finger-tighten the adapter into the detector base, then tighten an additional 1/8 turn
using a wrench.
