left in the open (GAS) position
when stations were not in use.
Keep the flow control valve
closed (OFF) at on all stations

degassing.
The gas flow rate is set too
high.
Decrease the flow rate by
reducing the regulator
pressure.
A flow control valve is
leaking.
Call the appropriate service
personnel.
No gas flow when the flow
control valve is opened.
Sample material in the gas
delivery tube is blocking gas
