Dynamic image analysis: Improving measurement of non-spherical particles
Thanks to advances in lasers, computers, automation, and other modern technologies, particle characterization methods are evolving rapidly. This article discusses one recently developed method: dynamic image analysis. Because it characterizes particle shape as well as size, the method can provide advantages over laser diffraction for sizing non-spherical particles.
While laser diffraction has become the most popular method for sizing particles a few millimeters in diameter or smaller, its sizing results for non-spherical particles contain unpredictable errors. A particle analysis method called dynamic image analysis provides advantages for sizing non-spherical particles by characterizing both particle size and shape.
