Abstract
Passing a sample of a liquid dispersion or emulsion of solid or immiscible liquid particles through one or more filters having a selected pore size less than 5000 A permits separation of the dispersed phase by particle size and/or separation of the dispersed phase from the continuous phase. The process is applicable to obtaining samples of dispersed particles, particularly latex, for analysis.
