medianpartikkelstørrelse
Medianpartikkelstørrelse is a statistical measure used to describe the size distribution of particles in a sample. It represents the particle size value that divides the distribution into two equal halves, meaning that 50% of the particles are smaller than this size and 50% are larger. Unlike the mean particle size, the median is less sensitive to outliers or extremely large/small particles, making it a robust indicator of the typical particle size. It is commonly used in fields such as materials science, pharmaceuticals, and environmental studies to characterize powders, suspensions, aerosols, and sediments. Determining the median particle size often involves techniques like laser diffraction, sieve analysis, or dynamic light scattering, where the cumulative distribution of particle sizes is analyzed. A lower median particle size indicates a finer sample, while a higher median particle size suggests a coarser sample. This parameter is crucial for understanding and controlling properties such as flowability, reactivity, and sedimentation rates.
