WebFlame ionization detector FID is a detector typically used with GC where the gaseous eluent is burnt in a flame, producing gas-phase ions of the analytes that are detected using an electrode. Additional developments have seen the coupling of this detector with … A flame ionization detector (FID) is a scientific instrument that measures analytes in a gas stream. It is frequently used as a detector in gas chromatography. The measurement of ion per unit time make this a mass sensitive instrument. Standalone FIDs can also be used in applications such as landfill gas … See more The first flame ionization detectors were developed simultaneously and independently in 1957 by McWilliam and Dewar at Imperial Chemical Industries of Australia and New Zealand (ICIANZ, see Orica history) … See more The operation of the FID is based on the detection of ions formed during combustion of organic compounds in a hydrogen See more The design of the flame ionization detector varies from manufacturer to manufacturer, but the principles are the same. Most commonly, the FID is attached to a gas chromatography system. The eluent exits the gas chromatography column (A) and … See more • Flame detector • Thermal conductivity detector • Gas chromatography See more FID measurements are usually reported "as methane," meaning as the quantity of methane which would produce the same response.
