Abstract
The rate of enzyme reaction is determined by determining of the quantity of enzyme, and deriving the rate of reaction per unit time of a reaction solution having an absorbance which is proportional to the time. A temperature correction coefficient which is used during the determination of the enzyme quantity is derived by temperature information which is supplied by a temperature sensor disposed within the reaction solution to be determined. An apparatus used for the determination of the rate of reaction comprises a means for containing the reaction solution, a temperature sensor directly disposed within the solution, a photoelectric transducer element responsive to light transmitting through the solution to determine the optical density of the solution, a logarithmic conversion circuit which converts the signal from the element into a corresponding absorbance signal, and a coefficient conversion circuit which is responsive to the combination of the absorbance signal and temperature information from the temperature sensor to correct a temperature coefficient.
