FPD - FlamePhotometricDetector
FPD, Dual FPD, FPD/FID, FID/Dual FPD
Either the single or dual FPD can be equippedwith an FID collector electrode and electrometer, whichwill
detect the hydrocarbon peaks at the same time the PMTs are responding to the sulfur and phosphorus
compounds. The FID response is not as sensitive as a pure FID because the hydrogen-rich lame is
optimized for sulfur and phosphorus detection, not hydrocarbon detection. Users can easily optimize the
sulfur-phosphorus response versus hydrocarbons response simply by adjusting the hydrogen/air mixture
with the includedEPCgas controls.
These three chromatograms are the FID/Dual FPD combination
detector responses to a 50ppmmalathion sample.
As shown in the close-ups
below, thesulfurFPDcandetect
a 5ppmmalathion sample, and
thephosphorusFPDcandetect
a 5ppbmalathion sample.
