FPD - SRI Instruments
Both the single or dual FPD can be equipped with an FID
collector electrode and electrometer, which will 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 flame is
optimized for sulfur and phosphorus detection, rather than
hydrocarbon detection. Users can easily optimize the sulfur-
phosphorus response versus hydrocarbons response simply by
adjusting the hydrogen/air mixture with the included EPC gas
controls.
The three chromatograms at left show the FID/Dual FPD
combination detector responses to a 50 ppm malathion sample.
The sulfur PMT in the FID/dual FPD combination
detector can detect a 5 ppm malathion sample
(left), and the phosphorus FPD can detect a 5 ppb
malathion sample (right).
