Abstract:
A zero headspace container that maintains a stable partial pressure of oxygen in a multi-analyte reference solution housed therein, comprising:(a) an inner layer forming the interior of the container and composed of a polymeric material that does not react with oxygen or has an oxygen reactivity that is sufficiently low so as to maintain the partial pressure of oxygen of a multi-analyte reference solution therein at a specified value Â±4 mm Hg; (b) an intermediate layer comprised of aluminum; (c) an outer layer that serves to protect the intermediate layer from physical damage; (d) a multi-analyte reference solution housed within the interior of the container; and (e) an access device housed totally within the interior of the container.
