Abstract:
Compositions comprising a reactive gas and a matrix gas are disclosed, as well as articles of manufacture and methods of making the articles. The methods of manufacturing preferably employ zeolites to remove moisture from the reactive gas and from the matrix gas, and then combine the moisture reduced gases either in a container, or prior to filling a container, which has been previously vacuum-baked and passivated. The invention produces stable standard gas compositions having improved shelf-life.

Articles Of Manufacture Containing Increased Stability Low Concentration Gases And Methods Of Making And Using The Same
Articles of manufacture and methods of making and using same concern a container having an internal space and a passivated internal metal surface. The container contains a composition of an acid gas and a balance gas contained within the internal space and in contact with the passivated internal metal surface. The stability of the acid gas concentration over time is enhanced.

Abstract:
Methods of passivating a metal surface are described, the methods comprising the steps of i) exposing the metal surface to a silicon-containing passivation material; ii) evacuating the metal surface; iii) exposing the treated surface to a gas composition having a concentration of reactive gas that is greater than an intended reactive gas concentration of gas to be transported by the metal surface; iv) evacuating the metal surface to remove substantially all of the gas composition to enable maintenance of an increased shelf-life, low concentration reactive gas at an intended concentration; and v) exposing the metal surface to the reactive gas at the intended reactive gas concentration. Manufactured products, high stability fluids, and methods of making same are also described.
Reactive Gases With Concentrations Of Increased Stability And Processes For Manufacturing Same
Methods of passivating a metal surface are described, the methods comprising the steps of exposing the metal surface to a silicon-containing passivation material, evacuating the metal surface, exposing the treated surface to a gas composition, having a concentration of reactive gas that is greater than an intended reactive gas concentration of gas to be transported by the metal surface, evacuating the metal surface to remove substantially all of the gas composition to enable maintenance of an increased shelf-life, low concentration reactive gas at an intended concentration, and exposing the metal surface to the reactive gas at the intended reactive gas concentration. Manufactured products, high stability fluids, and methods of making same are also described.
Articles Of Manufacture Containing Increased Stability Low Concentration Gases And Methods Of Making And Using The Same
Articles of manufacture and methods of making and using same concern a container having an internal space and a passivated internal metal surface. The container contains a composition of an acid gas and a balance gas contained within the internal space and in contact with the passivated internal metal surface. The stability of the acid gas concentration over time is enhanced.
