ANALYSIS APPARATUS AND AUTOMATIC ANALYSIS APPARATUS

摘要

PROBLEM TO BE SOLVED: To reduce influences by air bubbles and dusts on scattered light measurement with an automatic analysis apparatus.SOLUTION: A first wavelength 18a on a short wavelength side and a second wavelength 18b on a long wavelength side are emitted from a light source, and transmitted beams 19a, 19b and scattered beams 21a, 21b are received. Noise is estimated from a transmitted beam intensity ratio of the first wavelength and the second wavelength and from a change in amount of light of the scattered beam of the second wavelength. Subtraction is applied to a change in amount of light of the scattered beam of the first wavelength to reduce noise due to air bubbles and dusts.
