Title:
FLOW CELL AND OPTICAL SYSTEM FOR ANALYZING FLUID
Document Type and Number:
Japanese Patent JP2022172147
Kind Code:
A
Abstract:
To provide a flow cell and an optical analysis system that include a flow cell for analyzing a fluid sample in a chamber of the flow cell, for example, a chemical solution of a solvent and a solute in order to determine the density of the solute.SOLUTION: A flow cell 30 analyzing a fluid sample contains a reference material and includes at least one hollow chamber to contain the fluid sample. Opposing surfaces of the flow cell body each have at least one transparent portion. An optical path 56 for light traversing through the flow cell body is defined in part by the transparent portions. A switching mechanism 46 adjusts the amount of the reference material in the optical path to effect switching of the flow cell between a reference measurement state and a fluid sample measurement state. The reference measurement state corresponds to a first light intensity measurement and the fluid sample measurement state corresponds to a second light intensity measurement.SELECTED DRAWING: Figure 2
