  • Device for controlled vapor generation
    Patent number: 9506898
    Abstract: A device and method for generating vapor concentrations of a chemical. The device comprises a reservoir including a mixing chamber and a delta tube inlet section attached to the mixing chamber for supplying a first mixture of a carrier gas and a vapor of the chemical to the mixing chamber. A dilution gas inlet section is also attached to the mixing chamber and supplies a stream of dilution gas to the mixing chamber to blend with the first mixture of the carrier gas and the vapor of the chemical resulting in a second mixture of the carrier gas, the vapor of the chemical, and the dilution gas. An exit port section attached to the mixing chamber directs the second mixture of the carrier gas, the vapor of the chemical, and the dilution gas to an analyzer or system after it emerges from the reservoir.
