Even fullerene hydroxide particle sizes, which typify samples in
the single-digit nanometer region, can be measured with high
sensitivity and good reproducibility. This enables accurately
evaluating the dispersivity of particles in the single nanometer region. Raw Materials Evaluation of

● B (only)
△ A + B (mixture)
Even mixed samples can be measured. The IG method utilizes
the diffusion of a diffraction grating formed by particles to Normalized Particle Amount
measure samples, so the signal level is not dependent on
particle size. Therefore, this allows evaluating mixed samples. Product Information
In contrast, evaluating mixtures is difficult with methods that
use scattered light, because the signal level is proportional to Particle Diameter (nm)
the cube of the particle diameter, even if the volume is the same.

Example of Measuring Zinc Sulfide (ZnS) Particle Size Distribution (volumetric basis)

This example compares IG-1000 and TEM measurement
results (mean particle diameter).
These show a very consistent relationship between sizes.
