General description

Polystyrene-based microparticles (size: 8 μm) are a particle size reference standard, designed to determine the particle size distribution (PSD) profile of test samples.

Application

Used to calibrate, qualify and monitor the performance of particle size analyzers, surface scanning instruments and particle counters.
The polystyrene latex microbeads are also used:
  • to characterize sizing performance in impedance-based experiments.
  • to produce PS-μbead arrays by laser-induced forward transfer (LIFT) technique.
  • as a test standard for use in aerosol testbed to measure the sampling efficiency of aerosol inlet/manifold system

Features and Benefits

  • appropriate for routine equipment calibration checks 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 0.01 μm using a Coulter Multisizer.
