The following data was obtained by analyzing various sample particle groups of various sizes using the IG-1000 single nano particle size analyzer.
Fullerene hydroxide, which is a typical material of samples in the
single nano region, can be analyzed with high reproducibility.
Even with samples covering a wide distribution, there is no bias
toward larger particles, and the existence of smaller particles is
captured accurately.
Measurement results are not affected by minute quantities of
contamination. (The example shows the results obtained for a
sample with a distribution centering on a diameter of 50 nm that
contains a 1% concentration of 1-µm particles.)
Mixed samples can be evaluated. The IG method uses the diffusion of the diffraction grating created by particles and so 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 proportional to the cube of the particle diameter and so the evaluation of mixed samples is difficult.
