COMPLEX GEL PARTICLE DETECTOR AND OPERATION METHOD OF THE SAME, AND ENDOTOXIN CONCENTRATION MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a gel particle detector that simultaneously detects backscattered light components at a plurality of different angles to improve accuracy of measurement of gel particles.SOLUTION: A gel particle measuring apparatus is a detector for detecting scattered light from a sample cell 100 storing a mixed solution W containing a sample S and a reagent R. The detector comprises: an irradiation light guide member GFhaving an incident end connected to an incident light source 130, and emitting an incident beam Bm from an emission end to the sample cell 100; a plurality of first detection light guide members GFwhich introduce through incident ends a scattered light component forming a first angle with an optical axis of the incident beam Bm, of backscattered light components Lscattered in the mixed solution W in the sample cell 100 and returning toward the incident light source 130, and have emission ends each connected to a first light receiving element; a plurality of second detection light guide members GFwhich introduce through incident ends a scattered light component forming a second angle with an optical axis of the incident beam Bm, of the backscattered light components L, and have emission ends each connected to a second light receiving element.
