Efficient and precise: Particle size and shape measurement of sugar with Dynamic Image Analysis

Sieve analysis according to ICUMSA Method GS2/9-37 is the standard for particle sizing of crystal sugar. Officially, all labs follow these guidelines, and comparable results should be seen in round robin tests. On a closer look however, each lab
follows procedures that deviate slightly from those outlined in the ICUMSA Method. As a result, the size distributions measured by different labs vary remarkably. In this article we will discuss the typical deviations that can be found in the daily operation, and propose a new analysis method which provides
more reproducible and reliable results.
