Applications: Crystals, flakes, abrasives, silica, paint pigments, graphite and other lubricants; in general particles having more or less straight sides or facets and well-defined corners. Available measures: Polygon Order Polygon Order is the number of sides of the fitted polygon. Interior Angles Interior Angles are the interior angles of the fitted polygon. Since this is [...]

Applications: Straight fibers; thick short fibers; crystals; carbon fibers; in general any shape that isn’t circular where a length and width are needed. Available measures: Bounding Rectangle Width Bounding Rectangle Length BR Width and BR Length are the dimensions of the smallest rectangle (in area) that encloses the particle’s silhouette. Bounding Rectangle Aspect Ratio BRAR [...]

Applications: Certain metal powders and polymer powders; some crystals and abrasives; pollen. Available measures: Equivalent Elliptical Area Width EEAW is the width of an ellipse equal in area to the original shape, and having an aspect ratio the same as that of the bounding rectangle. Equivalent Elliptical Area Length EEAL is the length of an [...]

Applications: Powders having low aspect ratios, glass or plastic spheres, metal spheres, toners. Available measures: Equivalent Circular Area diameter ECAD is the diameter of a circle having the same area as the original shape. Equivalent Circular Perimeter diameter ECPD is the diameter of a circle having the same perimeter as the original shape. Bounding Circle [...]

Using size and shape measures, the Particle Insight can be trained to identify sub-classes of particles within a sample. For example, in the pharmaceutical industry, customers are able to see what percentage of particles are exipients and what percent are active ingredients. Two different techniques separation techniques are built into the Particle Insight software. The Expanded [...]

Only an imaging system can look at a sample particle by particle, and record data on each particle. This is its great advantage, and measure correlations are one way of exploiting that advantage to get maximum information from the data. The simple example below shows a powder in which Bounding Rectangle Width and Length generally [...]
