Flame ionization detector中文
WebEquations are given for relating flame ionization detector relative response factors to the effective carbon number (ECN) of neat and derivatized components. The ECN ap proach can be used for calculating relative response fac tors in cases where pure materials are not available for detector calibration. Examples of this approach are given for the analysis of … 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: Flame ionization detectors are relatively inexpensive to acquire and operate.
