Poly-disperse glass bead standards were developed as a better test of complete system performance for laser diffraction analyzers, compared to monodisperse polystyrene latex dispersions that are not representative of most materials tested on these instruments. In this report, PS240 was tested on the LA-960V2. PS240 is a 500 µm to 2000 µm, 7-gram single shot polydisperse glass bead standard produced by Whitehouse Scientific. Repeatability for all size classes was better than 2.5%, showing great repeatability for large size particles in wet dispersions.
