Abstract: The present paper deals with an argon microwave plasma torch atomic emission spectrometry detector(GC-MPT-AED) for gas chromatography, argon was used as the carrier gas, plasma support gas and make up gas. The effect of different kind of gases as the plasma scavenger gas, sheathing gas on the response characteristics for Sn, P, Si and B is discussed. Detection limits, dynamic range and relative standard deviation of the elements Sn, P, Si and B was studied, and the content of element P in Rogor emulsifying oil was also determined.

Key words: Gas chromatography, Argon microwave plasma torch, Atomic emission detector
