Priciples of Particle Sizing

Bookmark and Share

Particulates dispersed in a solution are normally subject to Brownian motion. The motion is slower with larger particles and faster with smaller particles. When laser light illuminates particles under the influence of Brownian motion, scattered light from the particles shows fluctuation corresponding to individual particles.The fluctuation is observed according to the pinhole type photon detection method, so that particle size and particle size distributions are calculated.

  • Measures particle size of samples suspended in liquids in the range of 0.1 nm to 12.30 μm w/sample suspension concentrations from 0.00001% to 40%
  • Well-established photon correlation spectroscopy technique conforms to ISO 13321 and ISO 22412
  • Combination of linear and log-scale correlators covers various sample characteristics
  • Variety of sample cells available
