Particle Size Distribution: Particle Analyzers :: Microtrac

The example below shows a particle size distribution with 5% oversize. Here, 95 % of the particles are below 1 mm, the oversize has a size of 1 - 1.25 mm. This can be quantified by Q3 (1 mm) = 95% or 1-Q3 (1 mm) = 5%. This example also shows that the addition of oversize increases the mean particle size, while the median remains unchanged.
