Micro particle size standard based on polystyrene monodisperse

Legal Information
Coulter is a trademark of Beckman Coulter, Inc.
Features and Benefits
suitable for routine instrument calibration checks, testing and corrections
available in 5 mL and 10 mL pack sizes as neat samples

General description
Monodisperse polystyrene based micro particles (size: 0.2 μm) are a particle size standard, ideal to determine particle size distribution (PSD) of test samples.
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.
Application
Used for equipment particle size calibration.
Monodisperse polystyrene latex particles are also used to find the PSD of colloidal dispersions.[1]
