The correct "option is (e)"
Explanation:
- A flame ionization detector ionizes the analyte through the use of an inert liquid.
- A Flame ionization detector (FID) has -
1) Hydrogen (H2)/air flame used for the passing of the gas
2) A collector plate used for the collection of ions
- The effluent released from the Gas Chromatography column passes through the hydrogen flame.
- The effluent released after entering the column of flame break down the organic molecules and forming the ions.
- The ions are detected by using a metal collector and are collected on a biased electrode giving an electric signal.
