An inductively coupled plasma atomic fluorescence spectrometer (ICP-AFS) for multielement analysis of unknown samples. The ICP-AFS spectrometer comprises a plasma stream atomizing a dispersed sample and directed along a central axis, a plurality of optical stations surrounding the central axis, each including an energizing illuminator and a fluorescence detector focused at the same region of the plasma stream, and a readout system for identifying the unknown samples. Preferably, the plasma stream is controlled by inductive coupling, the energizing illuminator is a modified hollow cathode lamp, the fluorescence detector includes an interference filter, and the readout system incorporates multiplexing and intermittent modulation of the energizing illuminators.
