<p>The invention provides an instrument, which incorporates control and measurement capabilities during generation of vaporized liquid, volatized liquid generator (220) includes a member (221) defining a flow passage or channel (223) capable of conducting a fluid or vapor to a first open end (225) and a power supply (229) for applying a voltage to the member (221) such that a current in the member heats the channel to temperature sufficient to volatilize a liquid material in the flow passage (223), such that the volatilized material expands out of the open end (225) of flow passage (223) and, if desired, mixes with the ambient air to form an aerosol. Liquid can be supplied from a source of material by a pump (235) other suitable mechanism.</p> |
