Abstract
A programmable aerosol generator forms a volatilized liquid by supplying a material in liquid form to a flow passage and heating the flow passage, such that the material volatilizes and expands out of an outlet of the channel. The volatilized material, if desired, mixes with ambient air such that volatilized material condenses to form the aerosol. An apparatus and method for generating such a volatilized liquid, as well as the control and methods of heating, are disclosed as an analytical tool useful for experimental use, a tool useful for production of commercial products or an inhaler device.
