92 Maintaining Your GC
6 Maintaining the Purged Packed Inlet
To Install a Packed Column Adapter on a Detector Fitting
1 Gather the following:
• 7/16- inch, 9/16- inch, and 1/2- inch wrenches
• Vespel/graphite ferrule (See “Consumables and Parts
for the Purged Packed Inlet” on page 68.)
• Brass column nut
• Lint- free gloves
• Adapter.
Select the appropriate adapter from one of the parts lists
shown below:
• Consumables and Parts for the FID (Packed columns
can only be installed on an adaptable FID.)
• Consumables and Parts for the TCD
• Consumables and Parts for the NPD
• Consumables and Parts for the FPD
• For uECD, 1/4- inch packed columns require no
adapter. For 1/8- inch packed columns, see
Consumables and Parts for the uECD.
2 Load the GC maintenance method and wait for the GC to
become ready.
3 Assemble a nut and a ferrule onto the adapter.
Be careful! The detector may be hot enough to cause burns. If the
detector is hot, wear heat-resistant gloves to protect your hands.
Wear clean, lint-free gloves to prevent contamination of parts with
dirt and skin oils.
