Abstract: A double detector system in which MPT is used as the atomic emission spectrometry detector and ionization detector simultaneously for gas chromatography is developed firstly. Argon is used as the plasma gas and oxygen as the sheath gas. The relative response coefficient and the detection limit of different organic compounds are determined. The atomic emission signal and ionic signal is firstly obtained at the same time.

Key words: Gas chromatography, Microwave plasma torch, Atomic emission spectrometric detector, Ionization detector, Relative response coefficient
