Abstract
A system and a method for generating a respirable dry powder aerosol () from a liquid solution or liquid suspension at a respirable dry powder aerosol volume flow (). A liquid aerosol generating nozzle () generates from the liquid solution or liquid suspension a liquid aerosol () that is diluted by dilution gas () and dried in a cylindrical evaporation chamber () to generate a dry powder aerosol () that is subsequently concentrated by a cylindrical single linear slit aerosol concentrator (). The system and method may include heliox as a gas, specifically dilution gas (), for enhancing both the drying process in the cylindrical evaporation chamber () and for enhancing the concentration efficiency, but also as a nozzle gas () for enhancing generating the liquid aerosol () from the liquid solution or liquid suspension.
