Column Installation and Conditioning
Connect
Column to
Injector
Your GC arrives ready for installation of an analytical column. On first
installation, a new column needs to be conditioned. Conditioning is
performed with the detector end of the column unattached.
Hot surfaces are exposed.
You may need to install and condition a new column after your GC has been
in use for some time. Reset all injector, detector and column ovens to
≤
50
°
C to avoid burn hazards when connecting column to injector and
detector parts inside the oven.
Prior to installing your column, check that the factory-installed injector is
equipped with the proper insert for your application. Factory-installed
injectors, other than the 1041, have a glass insert suitable for a variety of
applications. If your application calls for a different insert, replace the
factory-installed insert prior to installing your column. Refer to the Injector
section of the Operator’s Manual for instructions to replace the insert. The
factory-installed inserts for the injectors are shown below.

Nuts and
Ferrules for
Capillary
Columns
Capillary columns are generally installed with a
capillary column nut (P/N 03-949551-00) and a
single reversed ferrule, as shown in the
diagram. For connection to the TCD, a special
capillary adapter (P/N 03-925605-01) is used.
•
A Quick Connect Kit (P/N 03-925355-90)
facilitates easy connection of capillary
column to injector and detector. The kit
comes with instructions and contains:
column depth scale, knurled split nuts (2),
and graphite jacketed ferrules (2 each of 0.4,
0.5 and 0.8 mm ID, for 250 µm, 320 µm, and
530 µm columns respectively).
