Agilent recommends installing shutoff valves (not supplied) near the vial
pressurization and carrier gas fittings. Using the valves provides a fast way
to isolate the HS during troubleshooting and periods of inactivity.
Agilent provides hardware to plumb the instrument gases as
shown in Figure 10. In this example, the HS connects to a
7890A GC through the inlet septum. The GC provides carrier
gas control. The vial pressurization gas is connected to a
different supply than the carrier gas.
