Answer:A
In which of the following detectors, the carrier gas is excited by a radioactive source and the atoms of carrier gas are excited to metastable state?
A. Argon ionisation detector B. Thermionic emission detector C. Flame ionization detector D. Electron capture detector
Explanation: In Argon ionisation detector, the carrier gas is excited by a radioactive source and the atoms of carrier gas are excited to metastable state. It uses argon as carrier gas.
