Gas Chromatography Flame Photometric Detector

Brand : Shimadzu

Model : GC-2010 Plus

Brief description: Chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture (the relative amounts of such components can also be determined). In some situations, GC may help in identifying a compound. In preparative chromatography, GC can be used to prepare pure compounds from a mixture Flame photometric detector (FPD), which uses a photomultiplier tube to detect spectral lines of the compounds as they are burned in a flame. Compounds eluting off the column are carried into a hydrogen fueled flame which excites specific elements in the molecules, and the excited elements (P, S, Halogens, Some Metals) emit light of specific characteristic wavelengths. The emitted light is filtered and detected by a photomultiplier tube. With improvements in the inner structure and optics, the new FPD-2010 Plus, which is used for analysis of organic phosphorus compounds and sulphur compounds has been greatly improved. This detector supports analyses that require higher sensitivity, such as trace amount analysis of pesticides and analysis of odour substances.
