Particle sizing of powder
Three samples of Methocel powder were submitted for analysis. The powder was spread directly on a slide for evaluation. The measurements performed in this study were Area, Length, Circular Diameter, Sphericity, Aspect Ratio and Roughness.

Figure 2. Artifacts and particles sectionned by the field of view are eliminated.
Figure 3. Connected particles are isolated in the green bitplane using a sorting tool (Object Transfer by Limits) based on their irregular
shape. The Separate binary tool is then applied to disconnect some touching particles.
