Microwave-Supported Discharges:
Andrew T. Zander,Gary M. Hieftje +1 more
TL;DR: A review of microwave-induced plasmas (MIP) and their application to spectrochemical analysis is presented in this article, where the mechanism of formation and stabilization of a microwave discharge is explored and possible excitation processes involving analyte atoms are described.
Journal ArticleDOI
Volatilization of refractory compound forming elements from a graphite electrothermal atomization device for sample introduction into an inductively coupled argon plasma
G.F. Kirkbright,R.D. Snook +1 more
TL;DR: The use of a halocarbon/argon atmosphere in the sampling manifold of a graphite rod electrothermal vaporization device employed for the introduction of samples into a high-frequency, inductively coupled argon plasma source for optical emission spectroscopy is shown to permit sensitive determination of elements such as boron, molybdenum, zirconium, chromium, and tungsten which form refractory oxides or carbides as mentioned in this paper.
Journal ArticleDOI
Microwave plasma-atomic emission spectroscopy as a tool for the determination of copper, iron, manganese and zinc in animal feed and fertilizer
TL;DR: The new MP-AES platform can offer comparable or better performance compared to AA and/or ICP-OES with respect to routine analysis for a regulatory program.
Journal ArticleDOI
Considerations in the design of a microwave induced plasma utilizing the TM010 cavity for optical emission spectroscopy
A. Bollo-Kamara,E.G. Codding +1 more
TL;DR: In this article, a tangential plasma support gas flow (He or Ar) was used to generate a suspended plasma discharge which does not touch the wall of the discharge tube, and the resulting discharge has superior spatial and temporal stability compared to previously reported plasma discharges.
Journal ArticleDOI
Development and investigation of microwave plasma techniques in analytical atomic spectrometry
TL;DR: Microwave plasma (MWP) sources have found extensive use in spectrochemical analysis during the past decades as discussed by the authors, as the MWP offers some attractive features, it has been widely used either as an excitation source for atomic emission spectrometry (AES) or as an ionization source for mass spectrometer, and the use of MWPs as an atomization source is also appeared.

A cavity for microwave-induced plasmas operated in helium and argon at atmospheric pressure
TL;DR: In this article, a cavity is described by means of which a microwave induced plasma (MIP) can be obtained in argon and helium at atmospheric pressure using a low power microwave generator (P < 200 W).
Journal ArticleDOI
Evaluation of a microwave-induced plasma in helium at atmospheric pressure as an element-selective detector for gas chromatography
TL;DR: In this paper, the analytical performance of a microwave-induced plasma (MIP) generated at 2450 MHz in helium at atmospheric pressure with a cavity of novel design was evaluated for carbon, hydrogen, sulphur, chlorine, bromine and iodine.

Physical and Analytical Aspects of a Microwave Excited Plasma
TL;DR: In this paper, a microwave generator operated at about 100 W was used to maintain a narrow plasma (6 cm long × 0.3 mm diam) in flowing argon at atmospheric pressure.
