Thermo Fisher Scientific
Problem
FID noisy
Unable to calibrate FID
Excessive hydrogen
consumption (<8 hours of
run time for 2200 psi
hydrogen)
Flameout problems
Possible Reason
Broken ignitor
Dirty ignitor contacts
Battery charge low
Water/contamination in the
detector chamber
Erratic pump flow
Bad calibration
FID flame out
Span concentration not
properly set
Cal gases contaminated
Sample line/filter cups
contaminated
FID capsule contaminated or
faulty
Contaminated hydrogen tank
Internal detector fault or
contamination
Insufficient hydrogen pressure
Leaking hydrogen tank
Internal hydrogen leak
Sample hydrogen content too
high
Insufficient oxygen in the
sample (<14%)
Troubleshooting
Troubleshooting Guide
Solution/Action
Inspect ignitor coil on FID
capsule for breakage. If
broken, replace capsule.
Inspect/clean ignitor contacts
(not ignitor coils).
Charge battery pack.
Clean/replace FID capsule
and flame detector.
Clean/replace cups.
Clean/replace flame arrestor.
Service pump.
Ensure proper calibration.
Ignite FID.
Input correct span gas
concentration at CAL menu.
Use clean cal gases and
sampling equipment.
Clean/replace sample line.
Clean/replace filter cups.
Service pump.
Clean/replace FID capsule.
Replace hydrogen tank.
Call Thermo Fisher Scientific
Service Department.
Refill tank.
Replace tank.
Call Thermo Fisher Scientific
Service Department.
Use dilutor kit to achieve
concentration within the
dynamic range.
Use dilutor kit to dilute
sample with air
contaminating sufficient
oxygen.
