Abstract: A vaporizer for delivery of a volatile medium to a gas flow, the vaporizer comprising: a gas delivery unit (3) which receives a flow of gas and provides a flow of gas containing a metered amount of a vaporized medium; a reservoir unit (5) which contains a volatile medium and maintains a supply of the vaporized medium, wherein the reservoir unit is selectively fluidly connected to the gas delivery unit; a gas sensing unit (7) for sensing a flow rate and/or composition of the gas flow; a vaporized medium sensing unit (9) for sensing a flow rate of the vaporized medium; a manifold (10) which includes flow paths for the vaporized medium and fluidly connects the reservoir unit and the vaporized medium sensing unit; and a control unit (11) for controlling a flow rate of the gas flow and an amount of the vaporized medium which is metered into the gas flow.
