A New Selective-Nonselective Flame Photometric Detector for Gas Chromatography.

Microdetermination of phosphine by gas-liquid chromatography with microcoulometric, thermionic, and flame photometric detection

“…The FPD (also known as the flame-emission detector) is operated at hydrogen flame temperatures higher than for the TD, and enables specific detection of P, S, and other elements by photometric measurement at their characteristic emission lines. For the latter purpose, specific spectral bands in the hydrogen-rich flame can be selected with a monochromator (Juvet and Durbin, 1966; Zado and Juvet, 1966) or with interference filters. The FPD method of Brody and Chaney (1966) employs a Melpar, Inc. (Falls Church, Va.), narrow-band 526-µ optical interference filter that specifically isolates the band for P emission and a 394-µ narrow-band filter that selectively permits passage of emissions confined to the S VOL.…”

Portable continuous chromatographic coulometric sulfur emission analyzer

“…Recent literature articles indicate that the bromine titration cell and flame photometric detectors (Adams, 1967; Zado and Juvet, 1966) are the best of presently known detectors for sulfur compounds. Adams et al (1968) have reported sensitivities in the parts-per-billion range for' H2S using the bromine titration cell.…”

“…This detection system is highly specific for phosphorus in various oxidation states, for halides, for sulfur, and possibly for other elements. In 1966 JtJyET and DURBIN (1966) and ZADO and JUVET (1966) announced a flame-emission photometrie detection system, and BRODY and CHANEY (1966) reported another version of this same system; these detectors are also useful for phosphorus or sulfur determinations. Maximum specificity accrues with these and other specttometrie detectors (i.e., mass, infrared, and ultraviolet) now under evaluation in severallaboratories.…”

“…The carrier gas flow rate could not be measured at this reduced pressure but a gauge pressure that corresponded to a flow rate of 25 ml./minute at atmospheric pressure was used. JUVET and DURBIN (1966) and ZADO and JUVET (1966) have developed a flame-emission detector specific for phosphorus, sulfur, and many other elements. As shown in Figures 13 and 14, an elevated hydrogen-flame burner provides at convenient height (see Fig.…”
