|1. (WO2018088286) COMPONENT CONCENTRATION DETECTOR|
|Applicants:||TORAY ENGINEERING CO., LTD.
|Title:||COMPONENT CONCENTRATION DETECTOR|
The present invention provides a component concentration detector, which is capable of maintaining component concentration detection accuracy of a liquid, and reducing cost of an apparatus. Specifically, this component concentration detector, which detects component concentration in a liquid on the basis of light absorbance obtained by irradiating the liquid with light, is provided with: an irradiation unit that emits light; a light reception unit that receives the light emitted from the irradiation unit; a liquid cell unit, which is disposed between the irradiation unit and the light reception unit, and in which the liquid circulates; and a light collecting unit that collects light passed through the liquid in the liquid cell unit, said light having been emitted from the irradiation unit.
