Particle shape – An Important Parameter In Pharmaceutical ...

Particle shape and size data can be generated using automated image analysis techniques, complementing both microscopy and laser diffraction for particle characterization. In contrast to manual microscopy, image analysis generates statistically relevant data with no subjective bias, allowing shape, and its effects, to be studied systematically.

Particle shape - Ecetoc

Particle shape can modulate particle properties in several ways. Shape can have an impact on a particle's aerodynamic behaviour. This effect has been well described for fibres which can reach the deep lung despite their very long length because the aerodynamic diameter is proportional to the fibre diameter and not the length (Jones 1993).

Particle Shape - an overview | ScienceDirect Topics

The particle shape factor (χ) is a dimensionless constant used to relate drag force on an irregular particle moving in air to the particle's equivalent volume diameter (ICRP, 1994). The shape factor and the mass density are used to determine the particle's thermodynamic diameter in the model but in practice, the thermodynamic diameter can ...
