Connect Gas Supplies
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.
Figure 10 Standard plumbing configuration
See Table 8 for a summary of the acceptable gas types for
the HS.
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.
