    Abstract: Provided is a novel system and apparatus for producing primary standard gas mixtures. The system includes providing a gas permeation device having a constant diffusion rate into a temperature controlled enclosure; connecting a supply source of a component to the permeation device; routing the component from the gas permeation device to a product container until a desired amount of said component in the product container is reached; and supplying a balance of purified gas to the product container to obtain a known concentration of component in the primary standard gas mixture.

    Abstract: An apparatus for controlling the discharge of pressurized fluids from the outlet of a high pressure cylinder containing toxic hydridic or flammable compounds is provided. The apparatus contains a cylinder for holding a pressurized fluid in an at least partial gas phase; a cylinder port body threaded to the upper part of the cylinder in a sealed position; a dual port head valve assembly disposed within the cylinder port body, wherein a first port is utilized to fill the cylinder with a pressurized fluid, and a second port in fluid communication with an outlet of the cylinder to discharge the pressurized fluid; a gas flow discharge path defined in part by the second port body and the outlet, and further including a restricted flow path and a flow channel disposed upstream of the second port body, but wherein the gas flow discharge path does not include a restrictive element selected from the group of pressure regulators, check valves and restrictive flow orifices; and the restricted flow path limits the flow rate of the gas discharged from the cylinder to 5,000 sccm when the outlet of the cylinder is exposed to an atmospheric condition.

    Abstract: An apparatus (100) for controlling the discharge of pressurized fluids from the outlet of a high pressure cylinder (110) containing toxic hydridic or flammable compounds is provided. The apparatus (100) contains a cylinder (110) for holding a pressurized fluid in an at least partial gas phase; a cylinder port body (114) threaded to the upper part of the cylinder (110) in a sealed position; a dual port head valve assembly (116) disposed within the cylinder port body (114), wherein a first port (130) is utilized to fill the cylinder with a pressurized fluid, and a second port in fluid communication with an outlet of the cylinder (122) to discharge the pressurized fluid; a gas flow discharge path (12 0) defined in part by the second port body and the outlet, and further including a restricted flow path (130) and a flow channel disposed upstream of the second port body, but wherein the gas flow discharge path does not include a restrictive element selected from the group of pressure regulators, check valves and restrictive flow orifices; and the restricted flow path (13 0) limits the flow rate of the gas discharged from the cylinder to 5,000 seem when the outlet of the cylinder (110) is exposed to an atmospheric condition.
