Method and system for generating vapors of liquid solutions

摘要

A method and system for generating vapors of liquid solutions where a pneumatically modulated liquid delivery system maintains a defined flow rate for a liquid solution. The pneumatically modulated liquid delivery system includes a flow meter configured to measure a flow rate for the liquid solution flowing from a pressure vessel; a microcontroller configured to determine a pressure necessary to achieve the defined flow rate; and an electronic pressure control unit configured to adjust the pressure inside the pressure vessel. The system includes a nebulizer coupled to the pneumatically modulated liquid delivery system configured to receive the liquid solution from the pneumatically modulated liquid delivery system at the defined flow rate and configured to generate an aerosol of the liquid solution. A heat tube can vaporize the aerosol generated by the nebulizer.
