Abstract

Apparatus for enlarging the analytical capability of a photometric analyzer for segregating a first preselected analytical radiation wavelength band for passage through a first sample cell and segregating a second preselected analytical radiation wavelength band for passage through a second sample cell, after which emergent radiations from both sample cells are directed to a common radiation detector.
