Limitations of Simple Powder Flow Measurements and Particle Size Analysis for Bulk Powder Characterisation Freeman Technology is pleased to announce the release of a new application note “Limitations of Simple Powder Flow Measurements and Particle Size Analysis for Bulk Powder Characterisation”. An important point to appreciate about powders is that they are essentially three-phase systems consisting of solid particles, liquid (often relatively poorly controlled levels of water) and gas, typically air. This is why particle characterisation alone cannot reliably differentiate samples when ...
