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.

Overview of the 7890B GC
20 Getting Started
Automatic injectors
The optional Agilent 7693A automatic liquid sampler (ALS) with a sample
tray and bar code reader automates liquid sample processing, including
basic sample preparation. The modular design allows the autoinjector to
be easily moved from one inlet to another or from one GC to another. The
modular design also permits easy inlet maintenance. Also available is the
Agilent 7650 ALS injector, which provides similar injection capabilities
(without sample preparation).
Automatic gas sampling valves
The sampling valves are simple mechanical devices that introduce a
sample of fixed size into the carrier gas stream. Valves are most frequently
used to sample gases or liquids in constantly flowing streams.
