Title:
ANALYSIS DEVICE AND ANALYSIS METHOD
Document Type and Number:
WIPO Patent Application WO/2023/120231
Kind Code:
A1
Abstract:
The present invention makes it possible to analyze a plurality of components to be measured in a sample while simplifying an optical system, and provides an analysis device 100 that analyzes the concentration of components to be measured in the sample, the analysis device 100 comprising: a measuring cell 2 into which the sample is introduced; a light source 3 that irradiates the measuring cell 2 with light; a photodetector 4 that detects the light transmitted through the measuring cell 2; a variable filter 5 that is provided between the measuring cell 2 and the light source 3 or the photodetector 4, and changes the transmission wavelength depending on the light incident position; a filter moving mechanism 6 that moves the variable filter 5 to change the wavelength of light detected by the photodetector 4; and a concentration calculation unit 7 that calculates, on the basis of a detection signal of the photodetector 4, the concentration of the components to be measured.
