MULTI-ANALYTEN-REFERENZLÖSUNGEN MIT STABILEM PO2

摘要

For multi-analyte reference solutions with stable partial pressure of oxygen (pO2) zero headspace packaging is used. The reference solutions are packaged in containers lined with a material having low or no oxygen reactivity. An access device attached to the inside wall of such container for conducting a reference solution from the container into a blood analyser are disclosed. An access device for providing access to the contents of a package, said access device being wholly contained within said package and capable of preventing leakage of air into or out of said package when the package is punctured by a probe, said access device comprising: (a) a property or component that allows the positioning of said probe within said package, (b) a component which, when said package and access device are punctured by a probe, provides a seal around said probe, preventing leakage of air into or out of said package.
