Anti-degradation mechanisms for protecting aminated surfaces
First Claim
1. A method of protecting an amine-coated substrate surface, the method comprising:
- providing an amine-coated substrate;
providing a container for housing said amine-coated substrate;
providing a sorbent, having a composition made from either a single material or a combination of materials, said material characterized as being reactive with CO2 and having a high-surface energy of ≧
100 milli-joules/m2 for removing organic compounds from within said container; and
exposing said amine-coated substrate and an atmosphere within said container to said sorbent.

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.

7. A method of removing CO2 or organic contaminants from a package containing an amine-coated substrate, the method comprises:
- providing a carbonated substrate and either a sorbent material that is reactive with CO2 and having a high-surface energy of ≧
100 milli-joules/m2 for removing organic compounds, or a solution of either calcium, magnesium, or zinc hydroxide, (Ca(OH)2, Mg(OH)2, Zn(OH)2), with a pH value ≧
