Abstract: An analyzer provides conditions suitable for a reagent for performing latex immunoassay with a high sensitivity using a method of measuring scattered light. Irradiation light having a wavelength in the range of 0.65 to 0.75 ?m is used, and scattered light generated from a reaction solution is received at a light-receiving angle of 15° to 35° with respect to the irradiation direction during the rotational movement of the reaction container. The reagent contains latex particles the average peak particle diameter of which ranges from 0.3 ?m to 0.43 ?m and to which antibodies are sensitized. The reaction solution contains latex particles at a concentration at which the absorbance to irradiation light having a wavelength of 0.7 ?m is 0.25 abs to 1.10 abs, and a change in the amount of scattered light caused by the aggregation of the latex particles through antigens in a sample is measured and quantified.

Abstract: To reduce the influence of air bubbles and dust in measuring scattered light beams on an automatic analyzer. A light source emits a light beam with a first wavelength 18a on a shorter wavelength side and a light beam with a second wavelength 18b on a longer wavelength side, and then, transmitted light beams 19a and 19b and scattered light beams 21a and 21b are received. Noise is estimated from the ratio between the intensities of the transmitted light beams with the first wavelength and the second wavelength and a change in the amount of the scattered light beam with the second wavelength. Then, the estimated noise is subtracted from a change in the amount of the scattered light beam with the first wavelength, so that noise due to air bubbles and dust is reduced.

Abstract: There is provided a data processing method that reduces influences of air bubbles and dirt while maintaining changes in light amounts. Two scattering light photoreceivers are disposed in the forward direction. A photoreceiver 33a closer to the optical axis is taken to be a main angle photoreceiver, and a photoreceiver 33b further from the optical axis is taken to be a sub-angle photoreceiver. Noise is estimated based on the reaction process data of the sub-angle photoreceiver, and noise is reduced by subtracting the estimated noise from the reaction process data of the main angle photoreceiver.
