A new low-power microwave plasma source using microstrip technology for atomic emission spectrometry
TL;DR: In this paper, a low-power, compact microwave-induced plasma source for applications in atomic emission spectrometry at atmospheric pressure using microstrip technology is described, where the gas channel of about 1 mm2 is integrated in a fused silica dielectric wafer.
Journal ArticleDOI
A microwave-induced plasma based on microstrip technology and its use for the atomic emission spectrometric determination of mercury with the aid of the cold-vapor technique
TL;DR: Results obtained by calibration with aqueous solutions of Hg and with standard addition were found to be in good agreement with those of cold-vapor atomic absorption spectrometry.
Journal ArticleDOI
A low-power 2.45 GHz microwave induced helium plasma source at atmospheric pressure based on microstrip technology
TL;DR: In this article, the microstrip plasma (MSP) source for He is fabricated on sapphire substrates and the microstrips are designed for compact arrangements and for high electric field strengths in the plasma channel.
Journal ArticleDOI
Spatially resolved measurements and plasma tomography with respect to the rotational temperatures for a microwave plasma torch
TL;DR: In this paper, the analyte evaporation and desolvation capacity of the microwave plasma torch (MPT) as a new source for atomic spectrometry, the radially-resolved rotational temperatures as a good approximation for the gaskinetic temperatures were determined.
