LIGHT SCATTERING INTENSITY MEASURING METHOD AND DYNAMIC LIGHT SCATTERING MEASURING EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a light scattering intensity measuring method and dynamic light scattering measuring equipment using a low coherence light source for measuring the average grain diameters of fine grains or its distribution with high accuracy and a simple operation even for fluid dispersion containing fine grains with high density.

SOLUTION: Disclosed is a light scattering intensity measuring method for measuring the dynamic characteristics of fine grains dispersed in fluid dispersion by using a Mach-Zehnder type or Michelson type interferometer having a low coherence light source. This light scattering intensity measuring method includes inserting an irradiation/condensation part for irradiating the fine grains with the rays of light, and for condensing backward scattered light into the fluid dispersion in order to achieve the above mentioned measurement.
