Dynamic image analysis: Improving size measurement of nonspherical 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 nonspherical 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 nonspherical particles by characterizing both particle size and shape.
