Aug 08, 2011· Particle size distribution and size averages are determined by particle counting in a Coulter counter (e.g., Multisizer 3). It provides number, volume, mass, and surface area size distributions in one measurement, with an overall sizing range of 0.4 μm to 1,200 μm. Its response is unaffected by particle color, shape, composition or refractive

Jul 28, 2020· The distribution of particles sizes within an aerosol is essential information for understanding the behavior of that aerosol. The number of particles within certain size ranges is given by distributions specified by a count distribution if referring to number of particles, or a mass distribution if referring to particle mass.

When reporting a particle size distribution the most common format used even for image analysis systems is equivalent spherical diameter on the x axis and percent on the y axis. It isonly for elongated or fibrous particlesthat the x axis is typically displayed as length rather than equivalent spherical diameter.
