APPARATUS FOR GELATION MEASUREMENT AND SAMPLE CELL

摘要

It is intended to allow the concentration of a substance such as an endotoxin or ²-D glucan measured via gelation reactions to be measured in a short time and at a high sensitivity and a high specificity. In a measuring apparatus for measuring a target substance in a sample cell via a gelation reaction, a sample cell 13 for housing a specimen containing the substance to be measured and a solution containing a gelating reagent is irradiated with a laser beam from a semiconductor laser 11. The solution in the sample cell is stirred by a stir bar 25 to generate minute and uniform gel particles, which are caused to pass through the laser beam. Scattered light from the gel particles generated in the sample cell 13 is detected by a photodiode array 18, and a scattered-light intensity of the generated gel particles or the diameter and the number thereof is measured on time series by a computer 21 on the basis of a scattered-light detection output of the photodiode array.
