Abstract

The microwave torch named "torche a injection axiale" (TIA), i.e. torch with axial gas injection, was developed by the group of Moisan in 1993. This plasma torch can, depending on the geometry of the nozzle, excite many kinds of gases or mixtures, such as air, CO2 and noble gases. Therefore, it is a very promising plasma source for spectrochemical purposes. The plasmas sustained by the TIA normally expand in the open air and are typically 10 cm long and 2 mm in diameter. Microwave powers up to 2 kW can be used without the need for external cooling. In a previous paper we presented the electron density and temperature determined by Thomson scattering. In a plasma with helium as main gas ne ranges between 0.64 and 5.110 20 m-3 and Te is around 25000 K. In an argon plasma the electron temperature is lower and the electron density is higher: 17000 K and around 1021 m-3 respectively. In both cases the original nozzle is used (6 References).
