Abstract：Six kinds of particle size certified reference materials with nominal values of 0.6, 5, 10, 15, 25, 50 μm, coded with GBW (E) 120128~GBW (E) 120133, were been developed. The candidate monodisperse materials of CRMs were prepared by different polymerization techniques, and the average particle size was determined by scanning electron microscope. The results show that the developed CRMs have good homogeneity, and can be widely used in the particle size analyzer calibration.
Keywords: submicrometer, micrometer; particle size; certified reference materials
