Cause: If the FID is having ignition issues, it is due to the following causes: FID temperature : is too low. 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 to the concentration of organic species in the sample gas stream. To detect these … See more Advantages Flame ionization detectors are used very widely in gas chromatography because of a number of advantages. • Cost: … See more • Skoog, Douglas A., F.
