General description

Monodisperse polystyrene based micro particles (size: 6.0 μm) are a particle size standard, ideal for profiling particle size distribution (PSD) of test samples.

Application

Used to calibrate, qualify and monitor the performance of particle size analyzers, surface scanning instruments and particle counters.
Monodisperse polystyrene latex particles can also be used to:
  • investigate their effect on laser-induced breakdown spectroscopy (LIBS) emissions.
  • study the effect of polystyrene microplastics on microalgal photosynthesis and growth and oyster reproduction.

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.
