Procedure: Preliminary column conditioning steps
Procedure: Preliminary column conditioning steps
Materials required
Two 7/16-inch wrenches
No-hole ferrule and capillary nut for detector connection
1. Turn off the detectors. Shut off the detector support gases. It is especially
important to shut off hydrogen!
2. If the column to be conditioned is not already installed, connect one end to
an available inlet. If you are not sure how to install a column, see the instruc-
tions earlier in this chapter. DO NOT connect the remaining end to a detector!
3. If you plan to condition a capillary column in a split/splitless inlet, install the
proper liner and attach the column in the normal manner, making sure about
5 to 7 mm of column extends above (in front of) the column ferrule.
4. Cap the detector(s) fittings with the no-hole ferrule and column nut.
