Abstract

A device and methods for either protecting or restoring the delicate surface chemistry of amine-coated substrates adapted for biological assay uses from the deleterious effects of exposure to carbon dioxide and/or organic chemical compounds, which may arise in packaging or storage containers is provided. The device encompasses an enclosure, preferably hermetically sealed, a component susceptible to degradation from either carbon dioxide or organic compounds, and a sorbent, having a composition made from either a single material or a combination of materials, said material is characterized as being reactive with CO₂ and having a high-surface energy of ≧100 milli-joules/m² for removing organic compounds. The method can stabilize the surface chemistry and prolong the useful life of the coated substrate.

Claims

1-18. -18. (canceled)

19. A device comprising an enclosure, a component susceptible to degradation from either carbon dioxide or organic compounds, and a sorbent, having a composition made from either a single material or a combination of materials, said material is characterized as being reactive with CO₂ and having a high-surface energy of ≧

100 milli-joules/m² for removing organic compounds from within said enclosure.

20. The device according to claim 19, wherein said sorbent material is adapted to absorb residue CO₂ in hermetic packages to levels below 1 part per billion (ppb), over a temperature range from about −

40°

C., through ambient room temperature, to about 500°

C.

21. An object for containing an amine-coated inorganic substrate, the device comprising:
