Keys for Successful Analysis – Standard error calculation with Laser Diffraction

We have estimated the minimum mass required for a particular point in the distribution (e.g. x90) for a required standard error (e.g. 1%) given the top end size of the material and its density. In this presentation we will calculate the best standard error possible with a given mass of sample of known top end size, density given a point in the distribution to be determined. The results may surprise those users with measuring small amounts of material (20mg) with a reasonable top end size (say 200um).
