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.
Differential particle size distribution and cumulative particle size distribution are related to each other.
