OI Analytical's patented* Model 5383 Pulsed Flame Photometric Detector (PFPD) represents the latest advance in flame photometric detector design, optimizing selective detection of sulfur, phosphorus, and 26 other compounds.
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.
