90 Maintaining Your GC
6 Maintaining the Purged Packed Inlet
To Install a Packed Metal Column
1 Gather the following:
• 7/16- inch, 9/16- inch, and 1/2- inch wrenches
• Lint- free gloves
2 Load the GC maintenance method and wait for the GC to
become ready.
3 Prepare the packed metal column. (See “To Install
Ferrules on a Packed Metal Column” on page 99.)
4 Install the 1/8- inch or 1/4- inch packed column inlet
adapter, if necessary. (See “To Install an Adapter on the
Purged Packed Inlet” on page 81.)
5 Attach the column to the inlet adapter. Finger- tighten the
nut.
6 Tighten the nut an additional 1/4 turn with a wrench (for
a 1/8- inch column) or an additional 3/4 turn (for a
1/4- inch column).
Use two wrenches, one on the column nut and the other
on the adapter, to prevent the adapter from rotating.
7 Press [Config], [Column 1] or [Column 2], enter 0.00 in either
Length or Diameter, and identify the inlet and detector to
which the column is attached.
8 Condition the column, if necessary. (See “To Condition a
Packed Column” on page 97.)
Be careful! The oven, inlet, and/or detector may be hot enough to
cause burns. If the oven, inlet, or 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.
Do not use hydrogen as the carrier for conditioning! It could vent
into the oven and present an explosion hazard.
