for carrier gas and calibration streams, and contains the vents for sample and
column gases. The feed-through assembly comes in three configurations:
•
Without auxiliary heater
•
With 12 VDC auxiliary heater
•
With 24 VDC auxiliary heater
Assemblies with the auxiliary heater feature a heater with a temperature sensor
cable which makes connection to the analytical module and is replaceable. Note
that this cable comes in two configurations: 12 VDC and 24 VDC.

Inlets
All inlets have an internal, replaceable, 0.5 micron filters. Available inlets are:
•
1–4 sample stream inputs, calibration blend streams
•
1–3 sample streams with 1 dedicated auto cal stream, or
•
1–2 sample streams with 1–2 dedicated auto cal streams, or
•
1–4 sample streams with 1–2 manual calibration streams
•
1 carrier input stream

The 0.5 micron Filters should not be considered as a
replacement for the primary filtering system. Optional sample
conditioning modules are designed for this purpose.
2.3.4.2
Vents
Feed-through assembly vents do not have filters, but require vent tubing to be
attached and routed accordingly. These are:
•
2 column vents (CV1 and CV2)
•
1 sample vent (S1, S2, S3 and S4)
•
1 gauge port vent (GPV)
2.3.5
Analytical Module
The modular design of the analytical module is enhanced by the single bolt
removal feature. This assembly is comprised of the manifold and analytical
processor. These parts are not field-replaceable. The GC module is an important
part of the analytical module, but is field-replaceable.
The analytical module comes in two configurations: 12 VDC and 24 VDC.
