Photometric detector
WebOur 5383 Pulsed Flame Photometric Detector (PFPD) is linear, with an equimolar response to sulfur permitting selective measurement of individual sulfur species from low ppb to ppm levels and total sulfur as the sum of individual peaks. The unique capability to obtain simultaneous sulfur and hydrocarbon chromatograms from a single detector sets ... WebThe Flame Photometric Detector can detect sulfur compounds, such as H2S or SO2, down to about 200 ppb and phosphorus compounds to 10 ppb. While not 100% selective, the FPD is 100,000 times more sensitive to …
