  • Patent number: 11047786
    Abstract: The particle size distribution measuring apparatus includes a centrifugal sedimentation measuring mechanism and a dynamic light scattering measuring mechanism. The centrifugal sedimentation measuring mechanism causes particles to settle out by rotating a measurement cell accommodating particles dispersed in a dispersion medium and detects transmitted light by irradiating light to the measurement cell to measure a first particle size distribution on a basis of a change of transmitted light intensity of the transmitted light. The dynamic light scattering measuring mechanism detects scattered light occurred upon irradiation of light to particles so as to measure a second particle size distribution based on a change of scattered light intensity of the scattered light occurred due to Brownian motion of particles.
