Gas Chromatography Electron Capture Detector

Brand : Agilent Technologies

Model : 7890A

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. The electron capture detector is used for detecting electron-absorbing components (high electronegativity) such as halogenal compounds in the output stream of a gas chromatograph. The ECD uses a radioactive beta particle (electron) emitter in conjunction with a so-called makeup gas flowing through the detector chamberSeparation of a mixture of compounds into individual components.
