flame ionization detector

in gas chromatography
The gases emerging from the column are fed into a hydrogen flame across which an electrical potential is placed. Certain molecules ionize easily in the flame and the current produced is proportional to the instantaneous flow rate of the eluted component. The detector is relatively insensitive to inorganic molecules and is most used for organic compounds. Concentrations below \(1\ \text{ppmv}\) are easily detected. The linear dynamic range is between \(10^{3}\) and \(10^{5}\).
