Kendall Stokes · Answer 1

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.
