    Overview Knowledge Standards Terms
    A particle size analyzer measures the particle size distribution through laser diffraction or dynamic light scattering. The principle is that the scattering angle of light by particles is related to their size. Its function is to perform particle size analysis on samples such as powders and emulsions, and it is used for quality control in industries such as coatings, inks, and pharmaceuticals.
    Selection
    When selecting a particle size analyzer, consider whether the measurement range covers the particle size of the sample. Wet methods are suitable for liquid-dispersed samples, while dry methods are suitable for powders. Laser diffraction analyzers offer good versatility, while dynamic light scattering is suitable for nanoparticles. Pay attention to the instrument's repeatability and the applicable range of obscuration, ensuring that the accompanying software meets basic analysis needs.
