Claim Text:
1. An analyzer comprising: a cell containing a reaction solution obtained by mixing of a sample with a reagent; a light source unit configured to irradiate the cell with a light beam with a first wavelength and a light beam with a second wavelength on the same optical path, the second wavelength being longer than the first wavelength; a light receiving unit configured to receive a scattered light beam with the first wavelength and a scattered light beam with the second wavelength, the scattered light beams having been generated by interaction with the reaction solution in the cell; and a data processing unit configured to determine a signal by subtracting, from a signal representing a change in an amount of the scattered light beam with the first wavelength that has changed due to agglutination in the reaction solution, a signal that has been obtained by multiplying a change in an amount of the scattered light beam with the second wavelength by a reagent coefficient that depends on the reagent, and quantitatively determine an amount of a component in the sample on the basis of the determined signal, wherein a ratio between intensities of the light beam with the first wavelength and the light beam with the second wavelength that have passed through the cell is used as the reagent coefficient.
