What are Differential Particle Size Distribution and Cumulative Particle Size Distribution

  • Differential particle size distribution is the percentage of particles from the total that are within a specified size range; for example, 30% within 1-10um range, 50% within 10-20um range, and 20% within 20-30um range. Usually we say Diff. in AimSizer Particle Size Analyzers.

  • Cumulative particle size distribution is the sum of the differential distributions. The cumulative distribution is obtained by accumulation of differential distribution, for instance, 80% of the particles are smaller than 20um. Usually we say Cumu. in AimSizer Particle Size Analyzers
