Abstract:
1. A method for determining homogenization and/or reaction completion, comprising the steps of: (1) mixing a test liquid and a reagent liquid to obtain a liquid mixture; (2) measuring an optical property of said liquid mixture after the mixing continuously or a plurality of times discretely; (3) obtaining a relation between the measured value of the optical property obtained and the elapsed period of time since the start of the measurement after the mixing; and (4) determining, on the basis of said relation, whether said test liquid and said reagent liquid have been substantially homogeneously mixed with each other and/or a reaction between said test liquid and said reagent liquid has been substantially completed, wherein said step (3) is a step of obtaining (dS said step (4) is a step of determining that said test liquid and said reagent liquid have been substantially homogeneously mixed with each other and/or the reaction between said test liquid and said reagent liquid has been substantially completed, when the (dS
