Title:
OPTICAL MEASURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/235038
Kind Code:
A1
Abstract:
[Problem] To improve accuracy of measurement by removing variation in a measuring result in terms of the temperature of a measurement environment and cleanliness of a flow passage. [Solution] This optical measuring device is provided with, inside a housing 12, a flow passage for feeding a sample solution for measurement, and uses a fluid in which a complex is formed by an antigen-antibody reaction by adding, to the sample solution for measurement, a sample with an unknown antigen concentration and a fluorescently labeled an antibody solution with a known antibody concentration, the optical measuring device comprising: a Peltier element 41a for adjusting the temperature inside the housing 12; a temperature sensor for measuring the temperature inside the housing 12; and a control unit for operating the Peltier element 41a on the base of the detection by the temperature sensor. In addition, a pipe body constituting a flow passage for feeding the sample solution for measurement is composed of a copper pipe.
