Quality control, of either an intermediate material or final product, places a unique set of demands on an analytical tool. Rapid testing and sensitive differentiation between samples are essential, as is the need to measure a parameter that accurately reflects performance, during manufacture or within the customer's application. Historically for powders, all these issues have presented a challenge, but the last decade has seen significant advances in testing technology. Universal powder testers now measure a comprehensive set of dynamic, shear and bulk properties with exemplary reproducibility, making them a suitable choice for sensitive QC.
Powder behavior is complex and cannot yet be mathematically modeled in terms of the many variables that influence it. The ease, with which a powder flows, for example, depends on an array of primary variables, including particle size, shape and texture, but also on many system parameters such as degree of consolidation and moisture level. Poor control of any influential variable will compromise the reproducibility of an analytical technique.
