Three-Dimensional Modeling of an Inductively Coupled Plasma Torch for Spectroscopic Analysis

Inductively coupled plasma torches (ICPTs) are widely used tools in analytical spectroscopy. The deep understanding of the temperature field and flow pattern inside the discharge can be a useful tool for optimizing these devices. In this paper, a full 3-D model of an Ar ICPT has been applied to a commercial torch geometry. Temperature fields are shown together with a prediction of the pattern of the injected gas. Moreover, a prediction of the side view emission using volume rendering of the net emission coefficient has been presented.
