[Data] Evaluation Method for the Number of Fine Particles (High Dispersion of Fine Particles/Solution Dispersion)
Evaluation of the number concentration of fine powders! Measurement from both fine powder and solution dispersion perspectives.
This document discusses the issues related to powder evaluation, particle classification using the DMA method, and particle size distribution measurement through the ionization of powder dispersion solutions, focusing on the quantitative evaluation of fine powders. There are two methods for the quantitative evaluation of fine powders: evaluating them as fine powders and evaluating them after dispersion in a solution. In the "evaluation as fine powders," agglomerate-prone powders are assessed based on primary particle size. The proportion of their presence is analyzed through multi-channel measurements. In the "evaluation after dispersion in a solution," particle size distribution measurement from 2.5 nm allows for the evaluation not only of primary particle size but also of agglomeration states and particle classification.
