Introduction to Inlets

The septum purge line is near the septum where the sample is injected. A small amount of carrier gas exits through this line to sweep out any bleed. Each inlet has a different septum purge flow. The GC automatically sets the purge flow for EPC inlets,but you can measure it from the septum purge vent at the flow manifold if you like.
