The Assessment of a New Range of Large Monosized Polystyrene Spheres and their Potential as Calibration Material for Particle Size Analysis Equipment

Abstract

Large polystyrene spheres (nominally 5-, 7-, 10-, and 15-μm diameter) form a new range. The spheres have been sized using a Magiscan Image Analyzer, a scanning electron microscope, and a Coulter counter. Spheres of each nominal size have been found to have a tight size distribution.
