一般說明
Monodisperse polystyrene based micro particles (size: 200 μm) are a size standard, ideal for profiling particle size distribution (PSD) of a particle system.
The particle diameter of 200 μm is characterized using Olympus optical microscope. The measuring instruments are calibrated using standards obtained from the Community Bureau of Reference (BCR, Belgium: Standards RM 165, 166 or 167) and from the NIST (SRM 1690, 1691 or 1692).
