9)
The air flow rate is too high or too low
(FID).
10)
The hydrogen or air is contaminated.
11)
The water condenses in FID.
12)
The detector cable is in poor contact.
13)
The detector’s insulation turns smaller
(the ionization detector).
14)
The electrode, the nozzle or the base of
the detector is contaminated.
8)
Re-adjust the hydrogen flow rate.
9)
Re-regulate the air flow rate.
10)
Replace both the hydrogen filter and
the air filter.
11)
Remove the water by increasing the FID
temperature. (14) Replace the cable or
repair it.
12)
Clean the detector insulator.
13)
Clean the detector.
