In this regime, particle-particle interactions are not negligible. <\/p>\n<p>ISO 20998-3:2017 is applicable to colloids, dispersions, slurries, and emulsions. The typical particle size for such analysis ranges from 10 nm to 3 mm, although particles outside this range have also been successfully measured. Measurements can be made for concentrations of the dispersed phase ranging from about 5 % by volume to over 50 % by volume, depending on the density contrast between the continuous and the dispersed phases, the particle size, and the frequency range<sup>[<\/sup><sup>9<\/sup><sup>] [<\/sup><sup>10<\/sup><sup>]<\/sup>.
