Basic Theory of Particle Size Analysis by Sedimentation

rate of sedimentation for small particles is too low to give a practical analysis time, and because Brownian motion of small particles becomes too large to allow effective settling. A very narrow distribution of small particles will be reported as a broad distribution when the rate of particle diffusion is comparable to the sedimentation rate.

SEDIMENTATION AND ACCUMULATION RATES
