Abstract
A method for establishing a shelf life for getters is provided. The getter absorbs one or more gasses. One type of getter that can be used is desiccant to absorb moisture. The getter is sealed in a container that is impervious to the gas that is to be absorbed by the getter. The gas impervious container is placed within a gas previous first enclosure, which is positioned in a sealable second enclosure. A gas sensitive article is also located within the sealable enclosure. The sealable enclosure is sealed about the first enclosure and the article. The getter is activated to absorb any gas within the sealed enclosure by rupturing the container through the first and second enclosures. The second container retains the ruptured first container and the exposed getter.
