Abstract
Applications of a charge-coupled device (CCD) imaging spectrometer as a detection system for the determination of two-dimensional images of transient atomization events in a furnace atomization plasma emission spectrometric (FAPES) source are reviewed. Spectrally, spatially and temporally resolved images of the emission from analyte species (Ag(I), Ca(I) and Ca(II)) and plasma support gas (He(I)) in a 50 W He rf plasma are presented and the advantages of using a CCD camera system for fundamental characterization of vaporization, atomization, and ionization processes in the FAPES source are discussed. The limitations associated with the current system — insensitivity and limited spectral resolution — are highlighted and means of overcoming them are suggested.
