A moderate-power helium microwave discharge Is characterized as an element-selective detector for the gas chromatography of halogenated compounds. Plasma power and gas flow are optimized utilizing a mixture of chlorinated dioxins and pesticides. Not surprisingly, the lowest flows pos-sible with the tangential flow torch produced the best sensi-tivity. Unlike earlier solution nebullzatlon work, the higher plasma powers utilized led to poorer S//V. Multielement chromatograms are determined at several wavelengths cor-responding to the elemental emission available from specific compounds. Detection limits and linear ranges are presented. In addition to the quantitative Importance of this technique, elemental ratios (leading to empirical formulas) are deter-mined with high accuracy by using an off-line background correction scheme. On-line background correction schemes were also useful although Inferior to the off-line method. When no background correction Is employed, the accuracy of the elemental ratio Is considerably degraded.
