eBook An Introduction to Cascade Impaction Cascade impaction is a core analytical technique for orally inhaled and nasal drug products (OINDPs). Its ability to measure aerodynamic particle size metrics for active pharmaceutical ingredient(s) (APIs), as opposed to the entire formulation, sets it apart from other particle sizing techniques and ensures enduring relevance. Cascade impaction metrics quantify critical quality attributes for OINDPs, and compendial methods are applied from R&D through to QC. For those working with OINDPs a robust understanding of the basics of cascade impaction is key to its effective use. Copley Scientific has been making cascade impactors for over 30 years, and training analysts to use them for just as long. This ebook is a distillation of our expertise, our understanding of what people need to know and the issues that challenge. We hope you find it helpful.
