Characterization of a new type of nanoparticle generator for medical inhalation applications

Abstract: A new type of nanoparticle generator is being developed at Lund University. This project aimed to characterize it in order to produce a stable aerosol for medical inhalation applications. This project characterized size distributions during different parameter settings for the generator. The experimental work included assessing the effect of cleaning the generator between experiments for experimental runs all between 2 and 22 hours a piece. Other factors such as source material consumption and the effect of adjusting the different flows and temperatures were also investigated. Although that the results show mode switching it was found that a stable number concentration is possible for up to at least 20 hours and delivers nanoparticle within the range of 10-200 nanometers. Thus, with correct settings the generator satisfy the requested criteria to produce nanoparticles suitable for inhalation.
