Insert the column into the adapter, detector, or inlet liner until it bottoms.
Tighten the nut finger tight.
Adapter
Prepared column
If you are installing a column directly into the detector fitting:
• 1/4-in. column: tighten an additional 3/4 turn with a 9/16-in. wrench
• 1/8-in. column: tighten an additional 1/4 turn with a 7/16-in. wrench
If you are installing a column onto an adapter:
Tighten the column nut using two wrenches in opposition, one on the
column nut and the other on the liner or adapter body. This prevents the
liner or adapter from rotating while you tighten the column nut.
• 1/4-in. column: tighten an additional 3/4 turn with a 9/16-in. wrench
• 1/8-in. column: tighten an additional 1/4 turn with a 7/16-in. wrench
Establish a flow of carrier gas through the inlet. Heat the oven, inlet, and
detector to operating temperatures. Allow them to cool, and then retighten
the fittings.
Condition the column, if needed. (See
