Columns and Fittings
Inlet/detector liners/adapters
21
In addition, liners for the packed column inlet are available to accept
glass inserts (discussed later) for reduced reactivity, to trap nonvolatile
residues, or for use with an HP Series 530
capillary column.
No liner is used with 1/4•inchpacked glass columns. The long leg of
the column fits into the inlet body, replacing the liner. Packing and
glass wool plug must be below the tip of the needle for best results.
Metal columns are installed with a liner appropriate for the column
diameter.
If necessary, glass columns can be installed using a metal liner
(preferably those accepting a glass insert), but this is not
recommended. There may be problems with dead volume in
connections, and preventing contact of sample with metal surfaces.
