A flame detector is a sensor designed to detect and respond to the presence of a flame or fire, allowing flame detection. Responses to a detected flame depend on the installation, but can include sounding an alarm, deactivating a fuel line (such as a propane or a natural gas line), and activating a fire suppression system. When used in applications such as industrial furnaces, their role is to provide confirmation that the furnace is working properly; it can be used to turn off the i… WebIn principle, the Flame Photometric Detector (FPD) is identical to the FID with the addition of an S or P filter and a photomultiplier tube. Because also other atoms and (partial) molecules emit light, specific optical filters are used that only allow the light with specific sulphur or phosphorus wavelengths to pass.

Web(e) The flame photometric detector is based on the radiation emitted by sulfur and phosphorus containing molecules when the eluent is passed into a low-temperature hydrogen/air flame. (f) The flame ionization detector is based on ionization of the analyte in a small air/hydrogen flame. WebJan 1, 1976 · 9. The Flame Photometric Detector (FPD) The principle of flame photometry was first used in gas chromatography in 1961 [16] for the visual detection of chlorine-containing substances. In 1964, Huyten and Rijnders [42] constructed a flame photometric detector with a photomultiplier for the determination of halogens.
