Abstract
Apparatus and method for photometrically analyzing a constituent of interest in body or other fluids and well suited for kinetic determinations which are temperature-and-time dependent. There is provided a sample holder holding a cuvette supporting a liquid sample and other reactants among which is a trigger reactant to initiate the reaction which is analyzed. The trigger and the other reactants are initially isolated in the cuvette. The holder, one of a series, is moved periodically to move the cuvette, one of a series handled sequentially, to a temperature-sensing and preheating station, to a station where the contents of the cuvette are mixed to enable the reaction to proceed, to an optical station where the reaction is viewed for an optical density determination over a period of time under temperature conditions regulated within limits, and to a station for sensing the temperature of the mixture, by immersion of a temperature sensor therein, and supplying data for estimation of the real temperature during the optical determination for inclusion in the determination of the concentration of the constituent of interest, all in a relatively short period of time.
