Overview of the 7890B GC
Getting Started 19
The inlets
Inlets inject samples into the GC. The 7890B GC can have a maximum of
two inlets, identified as Front Inlet and Back Inlet.
A complete selection of inlets—split/splitless [0–100 psi and 0–150 psi],
multimode, purged packed, cool on- column, programmed temperature
vaporization, and volatiles interface—are available.
Samples can be injected into the inlets by an automatic sampling device
(such as an Agilent Automatic Liquid Sampler or Agilent Headspace
Sampler), or by hand using a syringe.
