An Internally Tuned TM₀₁₀ Microwave Resonant Cavity for Moderate Power Microwave-induced Plasmas

Abstract

During the last 20 years, the microwave-induced plasma (MIP) has become increasingly popular as a method of producing elemental emission. Using helium or argon primarily as support gases, these discharges are characterized by high spectral temperatures, resulting in the sensitive spectroscopic determination of a large number of elements including nonmetals, such as halogens. The primary focus of work in this area has dealt with the utilization of the MIP as an element-selective detector in gas chromatography. Various applications of the MIP appear in several current review articles.
