Abstract
The current invention provides a modulated pressure wave vapor generator suitable for use outside of the laboratory. The vapor generator of the current invention produces a controlled analyte vapor sample without using bulk movement of gas. Additionally, the current invention compensates for changes in the environment to ensure discharge of the preferred volume of analyte from the vapor generator. Finally, the current invention provides a method for generating a controlled volume of analyte vapor suitable for calibrating vapor sensors.
