Nut and Ferrule Installed on a Liner/Adapter

Figure 1-7

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

capillary

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.

WARNING

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.
