Abstract:

Diagnostic studies of the inductively coupled plasma (ICP) discharge are essential to the understanding of atomization, ionization, and excitation processes in this emission source. In these investigations, it is often desirable to view or scan distinct plasma regions. Several scanning methods have been described in which an imaging detector or moveable optical components scan while the plasma is held stationary. For emission signals, these techniques provide an acceptable method of data collection. However, when a source beam is used (i.e., for absorption, fluorescence, or scattering measurements), the problem of accurately and reproducibly positioning the source and detector optics becomes formidable.
