96 Model 5380 PFPD Operator’s Manual
Rev. 3.1
Detector Base Contains the combustor support (through which the
GC column passes) and the heater/temperature sensor,
which regulates the detector temperature.
Detector Body Contains the quartz combustor and acts as a support
for the light pipe to which the PMT housing assembly
is attached.
Detector Cap Contains the ignitor coil and vent through which spent
gases are discharged. It provides a support for the
ignitor assembly.
Detector Controller Contains the electronics that control the operation of
the PFPD and may also contain the pneumatics.
EEPROM Electronically Erasable Programmable Read-Only
Memory, which stores the PFPD’s specified start-up
operating parameters (specified in WinPulse).
EPC Electronic Pressure Control Module that may be
included in the HP 6890 GC.
Fine Adjust Needle Valve Controls the proportion of the H
2
/Air 1 mixture that
flows to the combustor and wall gas pathways.
Gate Time segment during the flame propagation lifetime
used to initiate and stop the integration period of the
output signal.
Gate Start Delay from start of flame propagation when integra-
tion of signal output is initiated.
Gate Stop Delay from start of flame propagation when integra-
tion of signal output is terminated.
GC Column Fused silica tube containing the stationary phase that
acts as a solvent for the sample components and
through which the sample is passed.

flow that is split between the combustor and wall
gas mixture using the fine adjust needle valve.
Heater Element Element used to increase the temperature of the PFPD.
Ignitor Heater element used to ignite the flame in the detector
cap.
Ignitor Current Electrical current flowing through the ignitor.
Interpolation Method used to obtain greater data frequency than
PFPD pulse rate. Linear and spline interpolation
methods are provided in WinPulse.
