To Replace the Filter in the Split Vent Trap for the
Split/Splitless Inlet
1 Gather the following:
• New split vent filter cartridge. See “Consumables and Parts for the Split/Splitless
Inlet” on page 42.
2 Launch the GC maintenance wizard: Maintenance > Inlets, select the inlet, then select
Perform Maintenance > Replace Split Vent Trap > Start Maintenance. The wizard will walk
through the steps needed to replace the filter (those same steps are repeated below).
Be careful! The oven and/or inlet may be hot enough to cause burns. If either is hot, wear
heat-resistant gloves to protect your hands.
The split vent trap may contain residual amounts of any samples or other chemicals you
have injected into the GC. Follow your company’s safety procedures for handling these types
of substances while replacing the trap filter cartridge.
3 Remove the pneumatics cover (top, back of GC). See “To Remove the Pneumatics
Cover” on page 19.

Figure 7.
