Ferrule Type
Encapsulated
graphite ferrule
See the Note
below.
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.
Note An optional adapter kit must be installed if you want to connect the column to
the injector and detector by using the encapsulated graphite ferrule. See
the Adapters for Encapsulated Graphite Ferrules"
