Configuring Carrier Gas Control
The 7697A headspace sampler is usually installed so that the
GC carrier gas flows through the HS. The GC method
parameters completely control the flow of carrier gas
through the HS–GC system. However, if using the optional
7697A Carrier Gas EPC Module Accessory, the HS can
control the carrier gas flow. Typical uses include connection
to a non- Agilent GC.

GC Control
This is the default installation. The GC carrier gas must be
plumbed from the GC EPC module to the Carrier fitting on
the back of the HS. See Figure 14.
