Flame ionization detector คือ
WebIntroduction. The flame ionization detector (FID) is the most sensitive gas chromatographic detector for hydrocarbons such as butane or hexane. With a linear range for 6 or 7 orders of magnitude (10 6 to 10 7) and limits of … WebThe flame ionization detector is a very common detector used in gas chromatography. The functioning principle of this detector is shown in Figure 8-21. The sample is brought to the detector via a pumping action, and it is burned in a flame. The flame commonly is generated with hydrogen and air. When a chemical compound is burned, it produces ...

WebA Flame ionization detector (FID) consists of a hydrogen (H 2)/air flame and a collector plate. The effluent from the GC column passes through the flame, which breaks down organic molecules and produces ions. The ions are collected on a biased electrode and produce an electrical signal. The FID is extremely sensitive with a large dynamic range ...
