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 Place GC in maintenance mode: Maintenance > Instrument > Perform Maintenance >
Maintenance Mode > Start Maintenance. Wait for the GC to become ready.
3 Prepare the packed metal column. See “To Install Ferrules on a Packed Metal Column” on
page 100.
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.
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 86.
Wear clean, lint-free gloves to prevent contamination of parts with dirt and skin oils.
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 Settings > Configuration > Columns, then select Columns 1 through 6. Select
Column Type > Packed, then choose your Inlet and Outlet Connection to identify the inlet
and detector to which the column is attached.
8 Scroll down to manually set your column temperatures.
Do not use hydrogen as the carrier for conditioning! It could vent into the oven and present an
explosion hazard.
9 Condition the column, if necessary. See “To Condition a Packed Column” on page 99.
10 Place GC in maintenance mode: Maintenance > Instrument > Perform Maintenance >
Maintenance Mode > Start Maintenance. Wait for the GC to become ready.
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.
11 If required, install a packed column adapter onto the detector column fitting. See “To
Install a Packed Column Adapter onto a Detector” on page 95.
12 Place a nut and ferrule onto the packed column.
