Columns and Fittings

Inlet inserts

Note: For the liner and insert for an HP Series 530 ¿ capillary column, if the column is already installed, a new insert may not seat properly in the liner; the column may prevent it from dropping completely into the liner.

If the insert does not drop completely into the liner, do not force it (either the liner or the column may shatter); instead, remove the column, seat the insert, and then replace the column.

5. Replace the septum and septum retainer nut.
