Title:
OPTICAL ANALYSIS SYSTEM AND CONTROL METHOD OF OPTICAL ANALYSIS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/075098
Kind Code:
A1
Abstract:
The purpose of the present invention is to achieve an optical analysis system which decreases the amount of liquid used in analysis and which enables long-term analysis. This optical analysis system is provided with: a first flow path which discharges and conveys liquid inside of a container; an intermediate branching for alternately outputting gas and liquid in the first flow path; a third flow path which conveys the liquid and gas flowing out of the intermediate branching; an analysis cell where the liquid and gas inside of the third flow path enter; a fourth flow path which is connected to the analysis cell and which discharges the liquid and gas after passing through the analysis cell; a pump which conveys the liquid and gas; and a control device. Further, the control device defines a reference liquid amount as a standard required for analysis, controls the intermediate branching and the pump such that the liquid and gas are controlled to alternately flow out into the third flow path, wherein a greater amount of gas than of liquid is made to flow into the third flow path.
