Ferrules
— Graphite ferrules, graphite Vespel® ferrules, and encapsulated graphite
ferrules are used for many column connections. See

Graphite ferrules
are a soft material that is porous to oxygen, making them suitable for most
applications except GC/MS interface connections. These easy-to-use ferrules form a soft grip with the
column and provide a stable seal. Graphite ferrule are re-usable.
Graphite/Vespel®
ferrules have a long lifetime and are compatible with GC/MS. These ferrules form
a strong grip with the column and cannot be reused as they form a permanent seal with the column.
They have a temperature limit of 350 °C, but must be re-tightened after initial temperature cycles.
