Abstract
A gel particle measuring apparatus detects a gel particle production starting point with high sensitivity, for measurement of a target substance in a sample by a gelation reaction. The gel particle measuring apparatus includes a sample cell accommodating a sample and a solution containing a reagent, a stirring device for stirring a mixed solution including the sample and the solution containing the reagent, a coherent light source that irradiates the mixed solution with coherent light, a transmitted light detecting device outside the sample cell, on the opposite side of the coherent light source, a transmitted light fluctuation detecting device for detecting a fluctuation component of the transmitted light, and a gel particle production determining device for determining at least the production state of gel particles, which leads to timing of phase transition of the mixed solution from a sol phase to a gel phase.
