General description

This polystyrene-based microparticle (size: 20 μm) size standard is ideal for profiling particle size distribution (PSD) of test samples.

Application

Used to standardize and monitor instrument particle size.
Also used:
  • to assess the effect of microplastics on zooplankton upon ingestion
  • to calibrate microfluidic device based on size measurements
  • in focused beam reflectance measurement (FBRM) based particle system characterization

Features and Benefits

  • suitable for routine instrument calibration checks, testing and corrections
  • available in 5 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 0.01 μm using a Coulter Multisizer.
