Patent ID: 7832550

Claim:
A manufactured product that contains a standard reactive gas with an extended shelf-life, the product comprising: a) a container having an internal space and a clean and passivated internal metal surface, said metal selected from aluminum and aluminum alloys; b) a composition comprising the reactive gas contained within the internal space and in contact with the clean passivated internal metal surface, the reactive gas having a concentration that is substantially maintained; and c) the clean and passivated internal metal surface comprising: i) a coating of a reaction product of a silicon-containing material and an oxygen-containing material that is deposited at a temperature of less than 74° C. and ii) an effective amount of the reactive gas adsorbed on the reaction product coating at a temperature of less than 74° C., the concentration of the reactive gas being adsorbed on the reaction coating being at least 500 times greater than the intended concentration of the reactive gas that is to be substantially maintained in the manufactured product.
