Introduction
OI Analytical’s Model 5380 Pulsed Flame Photometric Detector (PFPD) is the
latest advance in flame photometric detector design, optimized for the selective
detection of sulfur, phosphorus, and other compounds. The Model 5380 PFPD is
protected under U.S. Patent #5,153,673 and international patents issued to Aviv
Amirav, Tel Aviv University, Israel.
Detector Design
The Model 5380 PFPD consists of four principal components:
• Model 5380 Detector Assembly
• Model 5380 Detector Controller
• Pneumatics (either in the Detector Controller or in the GC)
• WinPulse™Software Program
The Model 5380 Detector Controller houses the signal processing, control, and
power supply electronics. The Detector Assembly consists of the base, combustor,
tower, ignitor cap, ignitor assembly, light pipe, optical filter, photomultiplier tube
(PMT) housing, PMT, heater, and temperature sensor. The pneumatics consist of
three flow controllers, a precision needle valve, and an associated gas manifold.
They are located either in the Detector Controller or within the pneumatics com-
partment of the GC system.
Principle of Operation
Operation of the Pulsed Flame Photometric Detector is based on a propagating
flame that terminates within a fused silica combustor. The gas phase reactions
produced by the propagating flame result in light emissions with specific lumines-
cence spectrum and lifetimes. The differences in specific emission lifetimes
combined with the kinetics of the propagating flame allow both time and wave-
length information to be used to improve the selectivity of the PFPD and to de-
crease the observed noise (which enhances sensitivity). Since a propagating flame
is used, lower combustible gas flow rates are used to increase the relative concen-
tration of the analyte. This is especially important for species, such as sulfur, that
form a dimer. In addition, the use of gated electronics permits the rejection of noise
occurring outside of the specified gate window. This further improves the
detectivity of the PFPD.
In order to retain all the sample compounds in the combustor for increased bright-
ness, a separate secondary flow of air and H2is continuously directed around the
outside of the combustor to separately fill the igniter cap with fresh combustible

gas mixture, which is richer with air for easier ignition. The primary and secondary
gas flows are known as combustor gas (COMB) and wall gas (WALL), respec-
tively. The separate pathways of these two gas mixtures within the detector are
shown schematically in Figure 1.1.
The pulsed flame propagation consists of a four phase cycle: replenishment of
combustible gases, ignition of gases, downward propagation of the flame (combus-
tion), and extinction of the flame (see Figure 1.2). The cycle begins with the
combustor gases (GC effluent, H2, and air) flushing out the combustor. Simulta-
neously, the wall gases (H2and air) sweep spent gases from the ignitor region
through a vent, and fill this space with a combustible gas mixture. The flame is
initiated when this gas mixture reaches the glowing ignitor coil. The flame then
propagates from the ignitor region through a convoluted pathway (to prevent light
from the ignitor reaching the PMT) and down into the combustor. If the gas
composition within the combustor is set correctly, the flame continues to propagate
toward the bottom of the combustor, where it terminates when all the combustor
gas has been consumed.
The pneumatic system of the PFPD has been designed to allow the operator to
regulate both the flow rates and the H2:Air composition of the combustor and wall
gases. Figure 1.3 provides a flow diagram of the pneumatic system. Three manual
or electronic gas flow controllers enable the operator to adjust the flow rates of H2
and air in the combustor gas and wall gas mixtures. The H2and Air 1 control

valves determine the composition of the gas mixture supply to the combustor. In
order to achieve rapid and consistent flame initiation at the ignitor, additional air is
added to the wall gas mixture by adjusting the Air 2 control valve. The relative
amounts of the H2:Air 1 gas mixture that flow to the combustor and ignitor regions
are controlled by a fine adjust needle valve.

In general, the gas flow controllers are used to optimize the H2:Air ratios in both
the wall and combustor regions while the fine adjust needle valve is used to
regulate the split of the H2:Air 1 mixture between the wall and combustor regions.
The relative rates of the wall and combustor flows can be adjusted so that the time
required to fill the ignitor volume with gas is equal to or slightly greater than the
time required to fill the combustor. If the ignitor fill time is less than the combustor
fill time, flame propagation becomes unstable with the flame alternately terminat-
ing at the top and the bottom of the combustor. This phenomenon is known as
“tick-tock.” Combustion of the GC analyte within the combustor volume is opti-
mized by using the fine adjust needle valve to adjust the detector to the tick-tock
condition and then increasing the combustor flow (or decreasing the ignitor flow)
slightly until the flame terminates only at the bottom of the combustor. This allows
the operator to easily manipulate the kinetics of the propagating flame and the
associated magnitude and lifetime of the chemiluminescence resulting from
combustion. (Refer to Chapter 5, “Operation,” for a discussion of pneumatic
settings that optimize the operating efficiency of the PFPD.)
The emission spectra detected by the PFPD are the product of the transmission of
the emitted photons through the light pipe and filter, and the spectral sensitivity of
the photomultiplier tube. Specific emission bands can be observed for species that
are produced in the PFPD. With a conventional flame photometric detector (FPD),
narrow band pass or interference filters are used to minimize interference from
carbon in the continuous flame. By contrast, the PFPD uses broad band pass filters
and time-based selectivity to minimize interference and increase optical through-
put. The background emission associated with the H2-rich flame in the combustor
consists of CH*, C2*, and OH* species that exist in the flame. While this emission
lasts less than 1 ms, the observed emission time of up to 4 ms (Figure 1.4) is due to
the dynamics of the flame propagating through the combustor. However, the sulfur
emission reaches its maximum 5–6 ms after the background emission is nearly
terminated. Thus sulfur and phosphorus have chemiluminescence lifetimes sub-

Introduction
stantially longer than the background analyte-free emission. Improvement in
detectivity (see Appendix B) and selectivity for sulfur and phosphorus is obtained
by using gated integration that rejects the unwanted CH*, C2*, and OH* chemilu-
minescence responses. (Refer to Chapter 5 for further discussion of PFPD opera-
tional parameters settings to optimize chemiluminescence responses.)
Since the PFPD is a pulsed detector (generating pulsed chemiluminescence), the
electronics are significantly different from the traditional FPD electronics. For the
PFPD, the most basic pulsed electronics consist of a fast electrometer, an event
(threshold) detection circuit, and a gated integrator. The output from the photomul-
tiplier tube is initially amplified by a fast electrometer. The subsequent output
signal is then digitized and passed through a gated integrator. The integration
interval is defined by the operator specified gates. The Detector Controller then
converts this electronic signal to an analog signal that is proportional to the inte-
grated signal.
The operator’s ability to optimize the operation of the PFPD is facilitated by the
use of WinPulse, a Windows®-based software package developed by OI Analytical.
WinPulse permits the operator to set up and optimize all of the PFPD’s operating
parameters. After these parameters have been uploaded to the Detector Controller,
the software is no longer required for the continued operation of the PFPD. If the
chromatographic conditions change dramatically, the operator can reactivate
WinPulse to reprogram the operational parameters.
Features
• Ability to “tune” selectivity of the PFPD results in fewer false positive identifi-
cations and decreasing the need for additional sample preparation.
• Improved sensitivity compared to many standard FPDs makes it easier to
detect lower quantities of trace-level contaminants and decreases the need for
sample concentration.
• Saves operational gas costs by using only 10% of the gas flow rate of standard FPDs.
• Equimolar sulfur chemiluminescence response that is independent of a
compound’s molecular structure allows calibration for complex samples.
• Real-time dual analog outputs enable acquisition of information for two
elements simultaneously.
• Optimization possible for up to 28 different elements.
• Automated timed events can be set for most detector parameters, which can
extend the performance range of a detector for a given application and often
minimizes the need for complicated chromatographic solutions to difficult
applications.
• No soot formation as a result of “self-cleaning” design.

• Constant reignition minimizes “flameout” problems, common in standard
FPDs, that are caused by water and other solvents.
• WinPulse software provides real-time display of the emission resulting from
each flame pulse. It facilitates detector setup and configuration, optimization
of operating parameters, and troubleshooting without the use of an oscillo-
scope.
• Post-run processing of data through the use of optional PFPDView™software.

Description of Components
Detector Cap serves to provide an attachment for the ignitor assembly and pro-
vides the path to the exhaust vent.
Flame Arrestor prevents the flame from propagating out through the vent.
Gas Lines are connected to the detector base. The lower gas line (COMB) pro-
vides the hydrogen-rich combustor gas that sweeps out the combustor base. The
upper gas line (WALL) provides an oxygen-rich gas mixture that sweeps out the
region between the detector body and the combustor, and provides gas to the
ignitor.
Heater Cable Assembly allows the host GC to control the temperature of the
PFPD sensor assembly.
Ignitor Assembly threads onto the detector cap’s ignitor tube.
Light Pipe is a quartz rod specifically designed for optimal transmission of the
chemiluminescence to the PMT.
Light Pipe Clamp compresses the light pipe O-ring, which provides a gastight
seal between the light pipe and the detector body.
Mounting Plate attaches the PFPD assembly to the top of the GC oven using
mounting screws.
Optical Filter mounts inside the PMT housing. An O-ring is used to keep the filter
from moving and to ensure that all the light from the light pipe passes through the
optical filter. The filter spectrally isolates specific chemiluminescence.
Photomultiplier Tube (PMT) converts light energy into electrical current. Increas-
ing the voltage applied to the PMT increases the current generated by the PMT.
PMT Housing contains the optical filters, PMT, PMT socket, and the electronic
cables for the signal and high voltage of the PMT.
PMT Socket attaches to the PMT connector pins. Voltage supply to the PMT and
electrical responses to chemiluminescence (resulting from flame propagation
through the combustor) from the PMT are transmitted through these pins.
Viton O-ring provides a light-tight seal between the PFPD detector body and the
PMT housing-filter assembly, and it prevents movement of the optical filter, light
leakage around the optical filter, and provides a “soft” bottoming to the PMT. The
Viton O-ring around the light pipe holds the light pipe in place when the light pipe
clamp is tightened.
