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

Optical enhancements and applications of rapid atomic emission spectrometry acousto-optic deflector background correction

“…The microwave-induced plasma (MIP) system consisted of a 500 W, 2.45 GHz microwave generator (Model 420B, Micro-Now, Skokie, IL, USA) and a copper Beenakker TM 010 cavity similar to that described by Haas et al 19 and Urh et al 20 The 12 L min 21 helium plasma gas ¯ow was directed through a tangential ¯ow, Te¯on insert-based quartz torch (9 mm id and 11 mm od) placed in the center of the cavity. The plasma was operated with a forward power of 350 to 450 W and minimal (#0 to 10 W) re¯ected power.…”

“…6) and the cavity is slightly modied. 7 Moreover, it is possible to introduce an aqueous aerosol without desolvation.…”

Moderate-power helium plasma as an element-selective detector for gas chromatography of dioxins and other halogenated compounds

“…Many workers have employed the low-power He-MIP for the determination of halogenated compounds. With the availability of moderate-power microwave generators for analytical work (11,12), a moderate-power He-MIP is potentially an attractive alternative as an excitation source for GC detection. The object of this work is to characterize a moderate-power He discharge as an element-selective detector for the gas chromatography of a variety of halogenated compounds, including the environmentally important dioxin EXPERIMENTAL SECTION Instrumentation.…”
