Pulsed Flame Photometric Detector (PFPD)
Compact and modular, the new, second generation 5383 Pulsed Flame Photometric GC Detector (PFPD) 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 PFPD uses significantly less gas than SCDs or FPDs and requires considerably less maintenance.
- Superior sensitivity and increased selectivity for S and P compared to conventional FPDs
- Linear, equimolar response for quick, easy calibrations
- Simultaneous mutually selective chromatograms for S/P, S/C, or S/N
- Inherent self-cleaning design completely eliminates soot formation, or “coking”, seen in other sulfur-selective detectors
- 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
Principal Applications:

* PFPDView is an optional Windows-based software package for use with a 5380 PFPD and WinPulse to reprocess chromatograms under different PFPD operating conditions.
PFPDView allows up to five different chromatograms to be viewed simultaneously to determine optimal parameters for an application or specific analysis. If gate parameters need to be changed, the resulting chromatogram can be viewed instantly.
After chromatograms are reviewed, they can be exported as a GC data file (AIA format) for import into a chromatographic data system. Viewing, reprocessing, printing, or reintegrating a GC run under new PFPD parameters are accomplished without rerunning the sample.
