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
