Flame ionization detector - Wikipedia
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] .

2005年12月1日 · Flame ionization detection (FID) is the most commonly used gas chromatography (GC) detection method. Flame ionization detectors respond to a wide assortment of hydrocarbons, have a large dynamic range, are...
Flame Ionization Detector - an overview | ScienceDirect Topics
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 Detector (FID) Principle - Inst Tools
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.
Flame ionization detector (FID), most popular GC detector
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.
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)
Flame Ionization Detector - an overview | ScienceDirect Topics
Flame ionization detector (FID) (Fig. 2-c) is a highly sensitive and universal mass detector with simple structure, wide use, good stability, quick response and low maintenance requirements (J. Wang et al., 2022; Zhai et al., 2022).
Flame Ionization Detector (FID) Principle - AutomationForum
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.
GC-FID | Gas Chromatography Flame Ionization Detector
The Flame Ionization Detector (FID) stands out as the predominant detection method in Gas Chromatography (GC) for identifying and measuring organic compounds. The operational principle of the FID is relatively straightforward, and a drawing of this detector could be easily visualized in Figure 1.
FID: Flame Ionisation detector - Chromedia
The flame ionization detector (FID) is an almost universal, highly sensitive detector for all organic compounds with a C-H bond. The FID measures the conductivity of a flame. With only the usual carrier gases and the detector gases hydrogen (as fuel) and air (as oxygen supplier) present, the conductivity is almost zero.
