Introduction to Headspace and to the 7694 Headspace Sampler
The 7694 Headspace Sampler
11
Pneumatics
The G1290 and G1883 headspace samplers use two flow paths: GC carrier gas
flow and flow for vial pressurization. You control the GC carrier gas flow using
a manual flow controller and the vial pressurization using a manual pressure
regulator.
The G1289 samplers uses the same gas streams, but all flow and pressure
control is provided by the 6890 GC.
In all models, two 1/8–inch Swagelok® bulkhead fittings are provided at the
rear of the pneumatic compartment for connecting lines for vial pressure and
carrier gas.
