WebAn ionisation probe for gas burners has an elongated body whose free end protrudes into the core of the flame and whose other end is joined to the flame controller. The body is housed within a... 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 … Meer weergeven 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) … Meer weergeven FID measurements are usually reported "as methane," meaning as the quantity of methane which would produce the same response. … Meer weergeven 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.
