2.3.5.2 Manifold Assembly
The manifold assembly is comprised of the manifold plate, heater, valves and
various cables to other major components. The manifold plate and heater maintain
constant temperature for the GC module and columns. The valve controls the
stream processing, carrier and calibrations gases. The cables complete the
information chain from the GC module to the analytical processor and the digital
controller assembly.
Figure 2-10 shows the manifold assembly. This is not a field-replaceable part.
