Abstract

A method and apparatus for measuring the unsteady sedimentation potential of particle in a suspension comprising: inserting at least a portion of the suspension of particles in a cell, the cell having a first electrode and a second electrode; vibrating the cell to accelerate the particles in suspension; and measuring the unsteady sedimentation potential of the particles across the first and second electrodes. The cell is vibrated at a frequency in the range between 0.0001-50 khz.
