A temperature and flow rate controlled capillary aerosol generator includes two heating zones (Z1, Z2) optionally separated by a region in which a pressure drop is induced. Power is metered or applied to the downstream second zone (Z2) to achieve a target resistance and a target temperature, while power is metered or applied to the upstream first zone (Z1) to achieve , a target mass flow rate exiting the second zone. A target temperature is achieved in the second zone to generate an aerosol from the liquid flowing through the generator at the desired mass flow rate.

Why it's free to use
- Filed December 3, 2001 and granted June 4, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 3, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 3, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
