Particle Size Distribution
Particle Size Distribution
Particle size distribution analysis is a crucial technique used to characterize the size distribution of particles in various materials such as powders, suspensions, emulsions, and aerosols. Particle size distribution influences material properties and behavior in processes such as flow, mixing, sedimentation, filtration, and drug delivery. Analytical methods such as laser diffraction, dynamic light scattering (DLS), sedimentation analysis, and microscopy are employed to measure particle size distribution accurately over a wide range of particle sizes.
Accurate particle size distribution analysis provides valuable insights into material properties, performance, and processing in industries such as pharmaceuticals, cosmetics, food, mining, and environmental engineering. In pharmaceuticals, it supports drug formulation and dosage design by optimizing particle size distribution for desired drug release kinetics, bioavailability, and stability. In cosmetics and personal care products, it aids in controlling product texture, appearance, and sensory properties by optimizing particle size distribution of ingredients such as pigments, emulsifiers, and thickeners. Moreover, particle size distribution analysis plays a crucial role in environmental monitoring and pollution control by assessing the dispersion, transport, and fate of particles in air, water, and soil environments.
