Capillary Column Use
Nut and Ferrule Installed on a Liner/Adapter
With one exception, liners/adapters are installed in the same manner;
if the liner/adapter has not been used before, a new ferrule must be
installed.
The single exception is the adapter to install an HP Series 530
column in a TCD without provision for capillary makeup gas (Part No.
18740•20950and 18740•20960). In this case, no ferrule is required to
form a seal with the detector base.
Note: A graphite ferrule is strongly recommended; since metal ferrules
tend to lock permanently onto the liner/adapter, their use may require
replacing the entire liner/adapter, should a permanent leak develop.
Exercise care! The oven, and/or inlet or detector fittings may be hot

enough to cause burns.
Note: The liner/adapter must be kept as clean as possible to prevent
introducing contamination into the inlet or detector. Use a clean,
lint•freecloth to remove fingerprints, etc., from the end of the
liner/adapter to be inserted into the inlet or detector base. CH
(methanol) may be used as a solvent.
