Particle Size and Shape Analysis
-Dynamic Image Analysis Method-



Dynamic image analysis is the method to measure the distribution of a particle size and a particle shape by the continuous photographing of particles dispersing in a solvent etc.

Particle shapes and aggregation state which can not be measured by the laser diffraction method can be observed by this method. Thousands to several tens of thousands of particles can be analyzed in a shorter time than the static image analysis.

* Our measurable range

  • Dynamic Image Analysis Method can measure more particles in a shorter time than Static Image Analysis Method, therefore, its cost is lower and its statistical reliability is higher than those of Static Image Analysis method.
  • Dynamic Image Analysis method can observe a shape of a particle which can not be measured by Laser Diffraction Method and also cam measure a length or a diameter of elongated grains.

Output data
