Abstract

Portions of a plurality of different samples are inserted automatically into an array of cuvettes which is advanced continuously or preferably intermittently along a circular path. Photometer means, preferably having several photometric detectors, are mounted in fixed orientation on a common support that advances rapidly compared with the movement of the cuvettes along a concentric circular path, such that radiation passing through each of the cuvettes is monitored many times by a specific photometric detector by the time that cuvette completes one circuit of its path. The photometric detectors can operate at several different wavelengths. Many different chemical reactions can be monitored at the same time. Detector signals are converted into digital signals proportional to absorbance and transmitted from the moving assemblage to a stationary receiver, e.g. as a pulsed train of light signals or by slip rings. <IMAGE>
