Description

General description

Monodisperse polystyrene based micro particles are a size standard, designed for profiling particle size distribution (PSD) of a particle system.
The particle diameter of 100 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).

Application

Used to calibrate and develop particle size analyzers.
Also used as a building block to synthesize ordered macroporous titania photonic balls.[1]

Features and Benefits

• suitable for routine instrument calibration checks, testing and corrections
• available in 5 mL pack size as a neat sample

Analysis Note

For every lot exact values of particle size and standard deviation are determined with an accuracy of 0.001 μm. The size determination of these particles follows procedures described by National Institute of Standards and Technology (NIST, USA) respectively by the Community Bureau of Reference (BCR), esp.:

• Transmission electron microscopy (TEM)
• Scanning electron microscope
• Light microscopy
• Coulter^™ counter with MDF-system

Calibration of equipment is carried out with NIST-respectively BCR-particle size standards.
