Gas chromatography with microwave plasma torch atomic emission spectrometry detector for the determination of Sn, P, Si and B

The present paper deals with an argon microwave plasma torch atomic emissio n 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 diff erent kind of gases as the plasma scavenger gas, sheathing gas on the respo nse characteristics for Sn, P, Si and B is discussed, Detection limits, dyn amic 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.
