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