Plumbing Diagram with a Pretreatment Box
For the GLA351-CCIA3, the external pump draws gas through the
SAMPLE INLET port (1/4”
Swagelok) on the back panel of the analyzer. The gas is filtered through a 10
µ
m filter
before entering the pressure controller, which throttles the flow to maintain the optical cell
at its’ target pressure. The gas is exhausted through the
TO EXT. PUMP port (3/8”
Swagelok).
