Pulsed Flame Photometric Detector (PFPD)

The superior sensitivity of the 5383 Pulsed Flame Photometric Detector (PFPD) makes it the instrument of choice for the analysis of sulfur, phosphorus, and other elements. Its linear, equimolar response to sulfur allows 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 it apart from other sulfur detection technologies.

Widely used in laboratory and process gas chromatographs to analyze sulfur species and total sulfur levels in liquid-phase petrochemicals, you will also find the Model 5383 hard at work analyzing organophosphorus pesticides, pharmaceuticals, flavor and fragrances, beverage-grade CO₂, chemical warfare agents, and more.

Compact and modular, the new, second-generation 5383 Pulsed Flame Photometric GC Detector offers greater ease of use, design flexibility, and analytical refinement than its predecessor, while retaining the proven technology features that laboratories around the world rely on for accurate results.

With a significant improvement in the signal processing and a 10-fold increase in sensitivity over most traditional FPDs, the detector makes accurate analysis of sulfur, phosphorus, and other elements easier than ever before. The intuitive, easy-to-use software suite with integrated monitoring and analysis capabilities provides a powerful tool for parameter optimization, data analysis, and more. Reliable and cost-effective, the 5383 uses significantly less gas than SCDs or FPDs and requires considerably less maintenance. 

Model 5383 PFPD Features

• Linear, equimolar response for quick, easy calibrations
• Simultaneous mutually selective chromatograms (e.g., S+C, or S+P)
• Self-cleaning design eliminates soot formation, or “coking”
• New, modular design with separate electronics and flow modules
• Better long-term stability and less maintenance than other S-selective detectors, such as SCD/XRF – Uses less gas than SCDs
