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.

Application

Used for equipment particle size calibration.
Monodisperse polystyrene latex particles are also used to find the PSD of colloidal dispersions.

Features and Benefits

  • suitable for routine instrument calibration checks, testing and corrections
  • available in 5 mL and 10 mL pack sizes as neat 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.
