The document discusses different types of detectors used in gas chromatography. It lists five common detectors: flame ionization, thermal conductivity, electron capture, flame photometric, and photoionization. The flame ionization detector is most commonly used for organic compound applications as it provides a specific response for separated components by producing an electric current signal that is amplified and measured.

11. A detector provides specific response for the
separated components. Majority of the organic
compound applications require flame ionization
detector.
There are following types of DETECTORS in gas
chromatography
1. Flame ionisation detector
2. Thermal conductivity detector
3. Electron capture detector
4. Flame photometric detector
5. Photo ionisation detector
6. Nitrogen phosphorus detector
