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] .

An FID, or Flame Ionization Detector, is the most common detector paired with gas chromatography instruments for analytical applications. But how does and FID work? An FID uses a flame to ionize organic compounds containing carbon.

Flame ionization detectors work on the principle of ions liberated in the combustion of the sample species. Here, the assumption is that sample compounds will ionize inside of a flame, whereas the carrier gas will not.

In a flame ionization detector (FID) the outflow is mixed with hydrogen and air and ignited. Ions and electrons are produced as a result of burning organic compounds; these can conduct electricity via the flame.

Flame Ionization Mechanism • The FID is a DESTRUCTIVE, mass sensing detector • Cations generated in the flame are counted and produce the detector signal • Analytes that have the greatest number of low oxidation state carbons produce the LARGEST signal • The FID will respond to ORGANIC compounds (C-H Bonds)

The flame ionization detector (FID) is the most widely used detector for gas chromatography because of its reliability, versatility, and ease of use. It responds to virtually any organic compound while generating little or no signal for common carrier gases.

A flame ionization detector is a commonly used detector in gas chromatography that measures the amount of analytes present in a sample by burning it in a flame and recording the resulting current generated by newly produced ions.

The flame ionization detector (FID) (see Table 1 under c) is the most used conventional detector for SCFAs detection in GC. FID is sensitive to molecules that are ionized in a hydrogen–air flame, including most carbon-containing compounds, and produces a current that varies proportionally to the amount of organic species in a sample [142] .

2023年5月7日 · The most accurate gas chromatographic detector for hydrocarbons like butane and hexane is the flame ionization detector (FID). In order to detect organic chemicals, flame ionization is the most reliable method.
