The procedures below assume the standard configuration: Plumbing as
shown in Figure 10, with GC carrier gas control using the inlet EPC module.
These procedures also assume that the GC is already plumbed and
operating, and that the GC is plumbed for helium carrier gas.
If your setup is different, connect your gases accordingly.
Materials needed:
• 1/8- inch Swagelok nut and ferrule set, stainless steel
• 1/16- inch Swagelok nut and ferrule set
• 1/16- inch to 1/8- inch flared stainless steel tubing,
1650 mm long
Tools required:
• 7/16- inch open- end wrenches
• 5/16- inch open- end wrenches
• Precision tubing cutter
For details on making Swagelok connections, see
Swagelok Connections."
Use only helium or nitrogen as vial pressurization gas. Never use
flammable gases for vial pressurization. Flammable gases create
an explosion hazard if used for vial pressurization.
1 Turn off the vial pressurization gas supply.
2 Use the 1/8- inch Swagelok nut and ferrules to connect
the 1/8- inch flared end of the stainless steel tubing to the
gas supply.
