General description

Silicon dioxide based microparticles are ideal to determine particle size distribution (PSD) profile of test samples.
The particle diameter of 5 μm is measured using Coulter Multisizer.

Application

Used for regular calibration and checking of particle size instruments. Also used:
  • to study transport properties of microscopic particles via heterogeneous media[1]
  • as a test standard to validate denoising method used in optical diffraction tomography[2]
  • in accelerated annealing experiments involving colloidal silica monolayers[3]
  • to evaluate the measurement accuracy of color-coded LED microscopy (cLEDscope) technique[4]
  • as a calibration standard in optical trapping system to measure surface mechanical properties[5]

Features and Benefits

  • suitable for routine instrument calibration monitoring, testing and corrections
  • particle size traceable to Community Bureau of Reference (BCR) standards
  • available in 5 mL pack size as a neat sample
