Assignee: HITACHI, LTD.
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 6:
7. A sample measurement method comprising:
storing a sample solution in a sample container;
irradiating the sample container with irradiation light from a first direction;
capturing an image of the sample solution based on light scattered by the sample solution from a second direction intersecting the first direction; and
calculating a degree of attenuation of a light amount of the image at a constant optical path length along the first direction based on the image and calculating an absorbance or a concentration of the sample solution according to the degree of attenuation,
wherein the degree of attenuation of the light amount of the image obtained for the sample solution to be measured is calculated, and the absorbance or the concentration of the sample solution corresponding to the degree of attenuation is calculated based on calibration data.
