Abstract (en)

[origin: EP0919252A1] A method of and apparatus for providing an aerosol are disclosed in which droplets are sprayed into an evaporation chamber (1) from an aerosol generation device (2) to provide an aerosol. The chamber has an air or gas inlet (13) and an outlet (4) from which the aerosol is withdrawn. The atmosphere within the chamber (1) is controlled in order to control the extent of droplet evaporation within the chamber, in turn to control the size of the aerosol droplets, by sensing the atmosphere within the chamber with a humidity or like sensor (12). The spraying of the droplets into the chamber by the aerosol generator (2) is controlled in dependence upon the output of the sensor (12). <IMAGE>
