et al., "Pulsed Flame Photometric Detector (PFPD) for Gas Chromatography," July 2015, https://www.tau.ac.il/chemistry/amirav/pfpd.html.
Organophosphorus pesticides were separated on Varian capillary column (30 m x 0.25 mm internal diameter fused silica capillary coated with VF-1701ms, 0.25 [micro]m film) but detected and quantified on a PFPD kept at 280[degrees]C.
The detection limits of the GC coupled with either ECD or PFPD were determined for each pesticide by injecting serially diluted standard mix.
Designing appropriate fire scenarios is very important in PFPD and fire risk analysis.
Adoption included adjustments based on the guidance given by the tutors of the PFPD Red PROFILE who advised me along the development of the project, the School schedule, and the availability of time and resources, among others.
A propagating flame that terminates within a quartz combustor is the operating principle of the PFPD. The gas-phase reactions produced by the propagating flame result in light emissions with element-specific wavelengths and lifetimes.
Tan solo tres de los 40 docentes-estudiantes de nuestro PFPD habian mirado con algun detenimiento el mapa de Africa.

These pulsed flame photometric detector (PFPD)-based systems provide low-level (ppb) sulfur analysis in a completely automated, low-maintenance GC system that can even generate its own S-standards using an integrated permeation tube oven.
The sensitivity, stability and low maintenance features of the PFPD result in reliable system for many sulfur monitoring applications in the beverage and petrochemical markets.
