Aerosol research laboratory
The department systematically and at the state-of-the-art level builds up facilities for experimental research into
aerosol transport and deposition. It is equipped with up-to-date instrumentation for preparation and experimental
research of liquid and solid particles. The research activities conducted currently at the laboratory include
elucidation of transport of various type particles as well as assessment of their deposition during inhalation into
human airways. The laboratory fundamental component is a test rig for aerosol preparation, its mixing with air and
measurement of flow operating parameters.
Other laboratory features include generation of liquid and solid aerosols sizing between 0.1 and 10 μm at concentrations up to 106 cm-3, measurement of particle motion, size, concentration and their morphology. The department know-how of complex biological models production is covered by a patent.
