<p>It is an object of the present invention to allow rapid and accurate measurement of the concentration of substances such as endotoxins, ²-D glucans and the like that is measured by gelation reactions. In a gelation-reaction measuring apparatus for measuring a target substance in a sample via a gelation reaction, a sample cell for housing a sample containing the target substance to be measured and a solution containing a reagent that gelates is irradiated with irradiation light from a light emitting diode 14. The solution in the sample cell 13 is stirred by a stir bar 25 to generate minute and uniform gel particles, through which the irradiation light passes. The light transmitted through the gel particles generated in the sample cell 13 is detected by a photodiode 22, and the detection output thereof is used to measure the concentration of the substance in the solution by a computer 21 on the basis of the lag time until the amount of transmitted light detected reaches or falls below a set level.</p> |
