Feed-through assembly

Independent sample streams are connected to the analyzer directly to the feed-through assembly
(see Figure 2-6), or through an optionally installed sample conditioning module. The feed-through
assembly also serves as the connection for carrier gas and calibration streams.

NOTICE – Equipment damage risk. The 0.5 micron filters should not be considered a
replacement for the primary filtering system. Optional sample conditioning modules are
designed for this purpose.
2.3.1

Configurations

The feed-through assembly comes in three configurations:
 Without auxiliary heater
 With 12 VDC auxiliary heater
 With 24 VDC auxiliary heater
The auxiliary heater has a replaceable temperature sensor cable which connects to the analytical
module. Note that this cable comes in two configurations: 12 VDC and 24 VDC.
2.3.2

Inlets

Feed-through assembly inlets take in the stream gas samples and carrier gas. They all have internal,
replaceable 0.5 micron filters. The inlets are:
 4 process stream inputs (S1, S2, S3, and S4)
 1 carrier gas input (CAR)
NOTICE – Equipment damage risk. The 0.5 micron filters should not be considered a
replacement for the primary filtering system. Optional sample conditioning modules are
designed for this purpose.
2.3.3

Vents

Feed-through assembly vents are outlets from which processed samples and used carrier gas exit the
analyzer. They do not have filters but require vent tubing to be attached and routed accordingly. The
vents are:
 2 column vents (CV1 and CV2)
 1 sample vent (SV)
 1 gauge port vent (GPV)
2.4

Analytical module

The analytical module assembly is comprised of a manifold, the analytical processor assembly, and the
GC module. The entire analytical module can be removed and/or replaced by loosening a single bolt.
