General description
Biotin-coated magnetic microparticles are a particle size standard, ideal for particle size distribution (PSD) analysis of a particle system.
The accurate diameter of 1 μm is determined by methods described by the National Institute of Standards and Technology (NIST, USA), such as:
Transmission electron microscopy
Scanning electron microscopy
Optical microscopy
COULTER COUNTER particle size analyzer with HDF system
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). This product comprises superparamagnetic polystyrene particles.
