Abstract

We investigate in this chapter another type of application using eddy currents. An Inductively Coupled Plasma torch (commonly referred to as ICP) is a technical device used to analyze a given sample (gas, solid or liquid prepared as an aerosol) by injecting it in a plasma (generally made of argon) (see Fig. 10.1). The sample atoms are thus ionized thanks to the high temperature of the plasma. In such devices, energy is supplied by Joule heating to maintain a plasma source to a given temperature. This source is useful to dissolve, vaporize and ionize gas and a sample to analyze. An ICP generally includes a sample introduction system (generally a nebulizer), an ICP torch, a radio frequency generator and a spectrometer. More detailed description and applications of ICP torches can be found for instance in [1, 25, 133].
