Pressure does not change when reagent flow is changed
The reagent gas regulator is closed
Check and, if necessary, open the reagent gas regulator.
The reagent gas regulator is set to the wrong pressure
Set the reagent gas regulator to 10 psi (70 kPa) for methane or to 3 to 10 psi
(20 to 70 kPa) for isobutane or ammonia.
The valve on the reagent gas bottle is closed
Check and, if necessary, open the valve on the reagent gas bottle.
The reagent gas supply is empty
Check and, if necessary, replace the reagent gas supply.
Reagent lines kinked, bent, pinched, or disconnected
Inspect the reagent lines and repair any defects. Check especially to make sure
the reagent line is connected to the rear of the flow module. Be sure the
methane line is connected to the Gas A inlet.
GC/MSD interface clogged or damaged
Check for flow and repair or replace components as indicated.
