Particle size analysis - Wikipedia
网页Particle size analysis, particle size measurement, or simply particle sizing, is the collective name of the technical procedures, or laboratory techniques which determines the size range, and/or the average, or mean size of the particles in a powder or liquid sample.
Particle Size Analysis - an overview | ScienceDirect Topics
网页Particle size analysis (PSA) is an important technique to measure the particle size distribution. In the pharmaceutical industry, the size of active ingredients influences the critical characteristics including content uniformity, dissolution, and absorption rates.
网页Microscopy or automated image analysis are the only techniques that can describe particle size using multiple values for particles with larger aspect ratios. WHICH SIZE TO MEASURE? A spherical particle can be described using a single number—the diameter— because every dimension is identical.
网页Particle size influences many properties of particulate materials and is a valuable indicator of quality and performance. This is true for powders, suspensions, emulsions, and aerosols. The size and shape of powders influences flow and compaction properties.
