The Inlets - Agilent Technologies 7820A Operating Manual

The Inlets

Operating Guide
Inlets are where samples are injected into the GC. The
Agilent 7820A GC can have a maximum of two inlets,
identified as Front Inlet and Back Inlet.
Two inlets—split/splitless and purged packed—are available.
The type of inlet chosen is based on the type of analysis
being done, the type of sample being analyzed, and the
column being used.
Samples can be injected into the inlets by hand using a
syringe, or an automatic sampling device (such as an Agilent
Automatic Liquid Sampler or Agilent Headspace Sampler).
