Abstract

PURPOSE:To make high-precision analyses even if the density of an item to be inspected would be low, by optically measuring time variation of chemical reaction by a mechanism which leads a reagent bland solution to a flow cell and then leads a sample solution to be inspected to the same flow cell. CONSTITUTION:As for a reaction speed measuring instrument which makes quantitative analyses of an item to be analyzed in an inspected sample by making an additive reagent react upon the inspected sample and by measuring optically the time variation of the chemical reaction, a reagent blank solution and sample solution are alternated on reaction line 18 and at the start of measurement, the reagent blank solution is led to cell 9 to measure its transmitting quantity by detector 14. Next, the inspected sample is led to cell 9 to measure its transmitting light quantity similarly. From a difference between a transmitting light quantity based upon the inspected sample solution and that based upon the reagent blank solution, absorbance is found by arithmetic part 16.
