- Executive summary:
Particle size distribution for the test item was determined using dynamic image analysis according to ISO 13322 -2 (Voelpker, 2017).
In total, 1,294,464 particles were measured via dynamic image analysis. Size of particles was calculated by EQPC (Circle of Equal Projection Area).
The following results had been determined:
Sauter mean diameter: 83.52 µm;
Volume mean diameter: 125.09 µm;
Mass median diameter: 105.76 µm
D 10 (mass) diameter: 45.39 µm;
D 90 (mass) diameter: 210.57 µm.
