| Abstract: | The utility of near-infrared atomic emission lines of C, F, S, Cl and Br for the determination of element ratios in organic compounds is evaluated. An atmospheric-pressure helium microwave-induced plasma is used to fragment sample molecules and excite their constituent atoms. The effects of plasma operating parameters such as power and flow rate, as well as the effects of spatial viewing position and plasma length are also investigated. |
