1.	In which of the following detectors, the carrier gas is excited by a radioactive source and the atoms of carrier gas are excited to a metastable state?(a) Argon ionisation detector(b) Thermionic emission detector(c) Flame ionization detector(d) Electron capture detectorI have been asked this question in an online quiz.Query is from Detection System of Gas Chromatography in division Chromatography of Analytical Instrumentation
Answer» The correct answer is (a) Argon IONISATION detector Explanation: In Argon ionisation detector, the carrier GAS is excited by a radioactive source and the atoms of carrier gas are excited to a metastable STATE. It uses argon as carrier gas.
