From traditional FPD methods to additional, harder to perform applications, the PFPD can be configured for a wide variety of methods with improved results. The PFPD provides a 10–100x increase in signal-to-noise and a 10x increase in selectivity over traditional FPDs while requiring minimal maintenance and decreased gas requirements.
The 5383 PFPD consists of a 5383 Detector assembly, 5383 Detector Controller, pneumatic components located either in the Detector Controller or in the gas chromatograph (GC), and WinPulse user interface software.
- 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
- Long-term stability and minimal maintenance
- Selective detection of 28 specific elements
