PHOTOREAGENT EVALUATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a photoreagent evaluating device capable of highly efficiently and accurately evaluating a photoreaction speed or photoreaction efficiency of a light reagent. SOLUTION: The primary light reflected by a beam splitter 21 by being emitted from a light source 10 is detected by a light detector 42. The primary light passing through the beam splitter 21 is made incident in a sample cell 31 by an incident window 313. The transmitted light passing through a photoreagent among the primary light incident in the sample cell 31 is emitted from an incident window 314 to be detected by a light detector 44. The secondary light generated when the primary light is made incident in the sample cell 31 is emitted from an emitting window 315 to be detected by a light detector 47. A photoreaction speed or photoreaction efficiency of the photoreagent in the sample cell 31 is evaluated on the basis of primary light intensity, transmitted light intensity and secondary light intensity by an evaluating part 50.
