A method and apparatus is disclosed which employs a pulse-controlled microdroplet fluid delivery system for precisely dispensing fragrances and other odor producing vapors. The pulse-controlled fluid delivery device is capable of ejecting microdroplets of fluid with a diameter less than 350 micrometers at a controlled ejection rate based upon ink-jet printing technology. The pulse-controlled fluid delivery system includes mechanisms for vaporizing the fluids and delivery of the vapors to the nose, which is controlled by a programmable system controller capable of real time data-driven dispensing with a multi-fluid capability. Synthesis of custom fragrances is made possible by a multijet programmed control system which adjusts dispensing rates of components. Calibration of a prior art "electronic nose" is disclosed. A precise calibration gas is produced in real-time to counteract the effect of drifting.

1. Apparatus for controlled dispensing of volatile material, comprising:a housing containing a target medium comprising a heater having a heating surface and an air-flow outlet; an electronically operated fluid droplet ejection device mounted with the housing, said ejection device having a fluid supply reservoir and a droplet ejection orifice aimed to deposit fluid droplets onto the heating surface; drive electronics operably connected to said ejection device; a system controller operably connected to the drive electronics and a power source whereby operating signals are delivered to the drive electronics to cause sequential droplets of fluid to be deposited onto the heating surface where they can be completely_volatilized and pass from the housing through the air-flow outlet, to be perceived by the mammalian_nose.
