Automatic analyzer

摘要

To be adapted to various types of latex reagents for detecting scattered light and thereby measuring agglutination reactions with high sensitivity while sufficiently ensuring integration time. To be adapted to various types of latex particles of different particle sizes, a plurality of light receivers are arranged in a plane perpendicular to the direction of cell movement by rotation of a cell disk. To ensure sufficient integration time, the angle between the optical axis of the irradiation light and each of a plurality of optical axes of scattered light viewed from above the cell is made equal to or less than 17.7° including a mounting error.

主权项

1. An automatic analyzer comprising:
a cell disk having a cell disposed on a circumference of the cell disk, the cell configured to hold a reaction mixture of a sample and a reagent mixed with each other inside the cell, and the cell disk configured to repeatedly rotate and terminate rotation; and a scattered light measuring unit including a light source and a plurality of light receivers, the scattered light measuring unit configured to irradiate the cell with irradiation light from the light source during rotation of the cell disk, and configured to measure, by using at least one of the plurality of light receivers, light scattered by the reaction mixture in the cell; wherein the plurality of light receivers are arranged in a plane perpendicular to the direction of movement of the cell caused by the rotation of the cell disk; and wherein the scattered light measuring unit is configured to receive the scattered light at each of a plurality of different scattering angles.
