The following data was obtained by analyzing various sample particle groups of various sizes using the IG-1000 Plus 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.
Silica Sample with Broad Distribution
Even with samples covering a wide distribution, there is no bias toward larger particles, and the existence of smaller particles is captured accurately.
Samples Containing Contamination
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.)
Analysis of Mixed Samples
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.
