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 flame. The generation of these ions is proportional … See more The design of the flame ionization detector varies from manufacturer to manufacturer, but the principles are the same. Most commonly, the FID … See more • Flame detector • Thermal conductivity detector • Gas chromatography • Active fire protection See more FID measurements are usually reported "as methane," meaning as the quantity of methane which would produce the same response. The same quantity of different chemicals produces different amounts of current, depending on the elemental composition of the … See more Advantages Flame ionization detectors are used very widely in gas chromatography because of a number of advantages. • Cost: Flame ionization detectors are relatively inexpensive to acquire and operate.

WebDetectors Flame Ionization Detector (FID) Ions produced by combustion are collected at a pair of polarized electrodes to give a signal (increase in current). This current is amplified and recorded. The ionization efficiency is low but sufficient enough to give excellent sensitivity and linearity.
