13 Detector
13.2 Hydrogen flame ionization detector (FID)
155
GC-2010 Plus
Q Ignition troubleshooting
When ignition has failed and the message “Ignition failed.” appears, check the following items.
13.2.2.5 Extinguishing the FID
This section describes how to extinguish the FID when the Advanced Pressure Control
(APC) is installed. Tighen the main valve of the cylinder after the extinction, if necessary.
Q Auto extinguisher
From the [SYSTEM] key main screen, press [STOP GC] (PF menu).
The detector temperature gradually decreases, supply of hydrogen and air is automatically
stopped, and the flame is extinguished.
When a time program is running or a stop time has been set, the detector gas is automati-
cally shut off at the end of the program, extinguishing the FID fmame.
Q Manual extinguishment
To extinguish the detector flame without waiting automatic extinguishment, set the gas con-
trol of “H2” and “Air” to “Off” on the [Det Gas] (PF menu) screen. The detector gas is shut off,
extinguishing the FID flame.
Cause Solution
Column is not connected.
Connect the column for FID to be ignited, and
ensure that carrier gas is flowing.
Gas leaks at the detector side column con-
nection.
Tighten the nut. Replace the ferrle.
Hydrogen is not supplied. Supply hydrogen.
Hydrogen flow rate is incorrect. Set the hydrogen flow rate to a proper value.
Air is not supplied. Supply air.
Air flow rate is incorrect. Set the air flow rate to a proper value.
Unused FID/FPD is set to “On”. Set unused detectors to “Off”.
FID jet is clogged.
Clean the FID jet.
Replace the FID jet.
Igniter filament is broken. Replace the igniter.
CAUTION
The cover of FID detector should be raised and set up using tweezers
for prevention of a scald in case of maintenance and inspection. Put
down the cover on its side using tweezers in case of analysis.
