Read More2016-8-25 · The parameter D90 should more correctly be labeled as Dv (90). It signifies the point in the size distribution, up to and including which, 90% of the total volume of material in the sample is ‘contained’. For example, if the D90 is 844nm, this means that 90% of the sample has a size of 844nm or smaller. The definition for D50 or Dv (50 ...

Read More2020-11-12 · In a particle size analysis report, in addition to the typical D10, D50, and D90, there is a value called "Span". It is calculated by the formula (Dv0.9-Dv0.1) / Dv0.5. Sometimes, when you measured a sample, the Span is very different from the previous one. Then, you may have to examine it with a microscope and observe the reason, perhaps the composition of the sample is different this

Read MoreParticle size distribution (PSD) is the means of measuring the number of particles by mass and size to calculate a size and mass range. D-values can be thought of as a mass division diameter. It is the diameter which, when all particles in a sample are arranged in order of ascending mass, divides the sample's mass into specified percentages.
