Sample preparation. Dispersing procedures for powders in liquids Ingestion-build-59651 Annex A Procedures for widening1 Scope This International Standard was developed to help particle size analysts make good dispersions from powder liquid combinations with which they are not experienced. It provides procedures for wetting a powder into a liquid; deagglomerating the wetted clumps; determining if solution composition can be adjusted to prevent reagglomeration; selecting dispersing agents to prevent reagglomeration; evaluating the stability of the dispersion against
