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 ¿ 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.

WARNING 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. CH2OH (methanol) may be used as a solvent.
