26 Agilent 7890B Installation
1 Installing the GC
3
Connect the traps and tubing. On/Off valves are not
essential, but are very useful when a tank or trap must be
changed. (If purchasing Agilent compliance services, install
an on/off valve for each inlet gas supply.)
Supplied fittings
Every GC ships with pre-assembled Tee fittings appropriate for
the number and types of inlets and detectors. (Customers who
ordered the pre-plumbed option will receive additional supplies
and fitting assemblies.)
Plumb to EPC flow modules
Inlet and detector EPC flow modules are mounted very close
together across the back of the GC. See Figure 7.
