ABSTRACT:
A centrifugal analyzer has a support for receiving a multicuvette rotor that defines a circumferential array of cuvettes, the analysis regions of the rotor being disposed circumferentially about the periphery of the support when the rotor is on the support. The rotor support is driven in rotation to subject the cuvettes to centrifugal force to position reaction products in respective analysis regions of the cuvettes for analysis, all of the analysis regions being moved along a fixed circular path as the drive means drives the rotor support. A plurality of fixed analysis channels are disposed along the fixed circular path about the periphery of the support, each analysis channel including means for directing radiation into analysis regions as they are moved along the path, and a radiation sensor aligned with the radiation directing means for receiving radiation emitted from analysis regions of the cuvette of the rotor and generating an output signal as a function of the emitted radiation, where each radiation has a well defined wave length. Processor apparatus connected to the plurality of radiation sensors receives concurrently output signals generated by the plurality of radiation sensors while the cuvettes of the rotor are being subjected to centrifugal force, and provides analytical data on reaction mixtures in the rotor cuvette analysis regions in response to the received output signals.
