The particles within a powder sample are present in a wide variety of sizes, shapes and compositions; with the requirements on their analysis and characterization being just as diverse. Analysis of ...

Dynamic light scattering (DLS) is a technique used for particle sizing of samples, typically in the sub-micron range. The technique measures the time-dependent fluctuations in the intensity of ...

Quantitative data from the literature show strong relationships among average particle size, powder densification, tensile strength, and hardness. The indentation-size effect forms the basis of the ...

The author examines the process of method development, with reference to ISO 13320:2009 and relevant monographs from the United States and European pharmacopoeias. Particle size is a critical quality ...

What Happens During a DLS Measurement? In a DLS measurement, particles diffusing by Brownian motion scatter incident light back to a detector, where interference of the light scattered by every ...
