A temperature and flow rate controlled capillary aerosol generator includes two heating zones optionally separated by a region in which a pressure drop is induced. Power is metered or applied to the downstream, second zone to achieve a target resistance, and therefore a target temperature, while power...http://www.google.fr/patents/US6501052?utm_source=gb-gplus-shareBrevet US6501052 - Aerosol generator having multiple heating zones and methods of use thereof
