Development and certification of a 300 nm monodisperse spherical particle reference material with SI-traceable diameter and mass

Accurate and SI-traceable characterization of particle diameter and mass is essential for improving the reliability of aerosol measurements and powder technologies. In this study, monodisperse spherical polystyrene latex (PSL) particles were developed as the Certified Reference Material of National Metrology Institute of Japan, NMIJ CRM 5722-a. Both the particle diameter and mass were determined using the electro-gravitational aerosol balance (EAB) method, Japan’s primary standard measurement te
