The use of plasmas for emission spectroscopy was reviewed based on a literature survey covering the period 1965 to 1980. Because it exploits differences in the elemental composition of the analytes, atomic spectroscopy has the potential of being one of the most selective, consistent, and versatile techniques of its kind. The field began in 1965 with the introduction of the effluent from a gas chromatograph into a microwave induced plasma (mip) permitting the monitoring of a variety of atomic line and diatomic band emissions to achieve selective detection. The technique has been applied as inductively coupled plasma (icp), direct current plasma (dcp) and the mip for selectively monitoring effluents from gas or liquid chromatographic separations. The theoretical and operational aspects of the plasma were briefly reviewed. The icp, mip, and dcp are well suited to the determination of metals. Radio frequency and microwave excitation sources have been useful in the determination of gases. Plasma emission spectroscopy also shows promise as a detector for organic compounds. Reductions of the sample volume in the plasma will undoubtedly improve the detection limit of the technique.
