ABSTRACT:
In an atomic absorption spectrophotometer for multielement analysis, the light from a plurality of light sources each of which emits the resonance lines of one associated looked-for element is superimposed into a single light beam by means of interconnected light guides. The light is directed onto a polychromator 64 via an optical coupler.
