Abstract

For numerous methods of granulometry, e.g. for sedimentation and wet sieve analysis, a suspension with a defined and constant dispersion state is an essential precondition. In many cases it is very difficult or not possible to fulfil this precondition in a simple way, since the information available on the complex physico-chemical conditions and their mutual interaction is not complete and can be extended only by extensive and partly empirical investigations. Furthermore, in many cases it is impossible to find a satisfactory answer to the question of the desirable dispersion state as a function of the aim of measurement. Ideally, the following requirements would have to be met:
  1. 1.

    The solid particles exist in the suspension individually, i.e. free of agglomerates.

     
  2. 2.

    The dispersion state shall not be modified in any measurable way in the time of the analysis.
