Qualitative Aspects of an Inductively Coupled Plasma in the Spectral Region between 120 and 185 nm

Investigations of the atomic emission lines produced by a variety of non-metals in the vacuum ultraviolet spectral region are reported. A number of promising analytical lines for oxygen, nitrogen, carbon, bromine, sulfur, and chlorine was observed between 120 and 185 nm using both photographic and electronic detection. A unique experimental configuration employing a side-arm torch which directly couples to the vacuum spectrometer/spectrograph is described.
