Abstract:
A process for supplying a gas reagent, comprising:providing a storage and dispensing vessel containing a solid-phase physical sorbent medium having a physically sorptive affinity for said gas reagent; physically sorptively loading on said solid-phase physical sorbent medium a sorbate gas, to yield a sorbate gas-loaded physical sorbent medium; mounting the storage and dispensing vessel in a gas cabinet defining an enclosure including therein a gas dispensing manifold; coupling the gas storage and dispensing vessel in gas flow communication with the gas dispensing manifold; selectively desorbing sorbate gas from the sorbate gas-loaded physical sorbent medium, by reduced pressure desorption, for flow of desorbed sorbate gas into the gas dispensing manifold and dispensing thereof; wherein the solid-phase physical sorbent medium is devoid of trace components selected from the group consisting of water. metals and oxidic transition metal species in a sufficient concentration to decompose the sorbate gas in said storage and dispensing vessel.
