Why Instrument Variety Matters in Laser Diffraction Testing

Laser diffraction is a technique that determines a volume-weighted particle size distribution based on the angles at which a dispersion of particles scatter laser light. This technique is commonly used as a quality control test and benefits many

What is Dispersion and Why Is It Important?

Particle characterization—the determination of a material’s physical and chemical properties—is a cornerstone of industries such as pharmaceuticals, materials science, biology, and environmental science. Among these properties, particle size is particularly crucial, influencing a material’s performance, stability, and application.
