Abstract
The present invention includes: a cell holding body that holds a measurement cell housing a measurement sample and a dispersion medium; a cover attached to the cell holding body so as to cover the measurement cell; a rotation section that rotates the cell holding body and applies centrifugal force to the measurement cell; a light source that is provided on one side of a rotation passage region of the measurement cell and irradiates the cell with light; a photodetector that is provided on another side of the rotation passage region of the measurement cell and detects light transmitted through the cell; and a particle diameter distribution arithmetic section that acquires a light intensity signal from the photodetector and calculates a particle diameter distribution. The rotation passage region of the cover is located inside an optical path of light passing between the light source and the photodetector.
