    Type of gas detector used in gas chromatography

    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 ions per unit time makes this a mass sensitive instrument.[1] Standalone FIDs can also be used in applications such as landfill gas monitoring, fugitive emissions monitoring and internal combustion engine emissions measurement[2] in stationary or portable instruments.

    History

    [edit]

    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) Central Research Laboratory, Ascot Vale, Melbourne, Australia.[3][4][5] and by Harley and Pretorius at the University of Pretoria in Pretoria, South Africa.[6]

    In 1959, Perkin Elmer Corp.

    included a flame ionization detector in its Vapor Fractometer.[7]
