Measurement Data Analysis of Mixed Samples

The following data was obtained by analyzing various sample particle groups of various sizes. The IG method uses the diffusion of the diffraction grating created by particles; therefore, the
signal size does not depend on the particle size. This means that evaluation of mixed samples is
possible. With methods based on scattered light, even if the volume is the same, the signal size is

Fullerene Hydroxide Particle Size Distribution (Volumetric Basis) proportional to the cube of the particle diameter, making evaluation of mixed samples difficult.
