The bulk solids industry has long been in need of a rapid, cost-e!ective, concise QA/QC test for benchmarked powder formulations. The importance of this type of test is imperative to ensure powder jams and flow issues are caught before a major production run is implemented (COMPROMISED). While the test needs to be quick and accurate, too often accuracy is sacrificed for speed. This “need for speed” usually employs an empirical type of test. This is a reflection of the cost of test equipment and the time it takes to run a test. But, a method does exist that addresses the requirements for a QA/QC test: cost, speed and accuracy.
