Automated determination of particle-size distributions of dispersions by analytical ultracentrifugation

The ultracentrifugation method for determining the particle-size distribution of dispersions has been automated and its precision and capacity improved.A mixture of seven monodisperse calibration latices can be analysed and two lattices with a difference in diameter of 10% can be resolved by a base-line separation.This paper was presented at the VI. Symposium on Analytical Ultracentrifugation, Marburg, FRG, February 16–17, 1989.
