Particle size distribution refers to the analysis and measurement of the sizes of particles present in a sample or substance. This information is important for various industries and applications, such as pharmaceuticals, food processing, environmental monitoring, and material science. Particle size distribution analysis helps in determining the physical properties of the particles, such as shape, surface area, and porosity, which can impact the performance and quality of the material. Methods for measuring particle size distribution include laser diffraction, microscopy, and sedimentation techniques. Understanding the particle size distribution of a sample can help in optimizing processes, ensuring product consistency, and identifying potential issues or contaminants.
