Answer:B
Flame ionization detectors are sensitive to which of the following gases?
A. Carbon dioxide B. Methane C. Carbon monoxide D. Sulphur dioxide
Explanation: Flame ionization detectors are sensitive to methane since, they are sensitive to organic compounds. They are insensitive to non-combustible gases. Hence, they are not sensitive to carbon monoxide, carbon dioxide and sulphur dioxide.
