Abstract
Currently, the characterisation of particle release from nanostructured powders is realised based on different release scenarios, which were typically designed to describe real powder handling processes. Most of these scenarios base on short term stress situations (e.g. drop down, mixing) and are thus accompanied with dynamic changes of the particle number concentration, which complicates both the process characterisation and the release characterisation. In this study, two continuous release processes for weak and intense dispersion of powder agglomerates were analysed based on considerations regarding energetic and instrumental impact.
