ABSTRACT:
A getter system is provided for use with an evacuated container such as a vacuum insulation panel. The getter system has a first, activated getter material capable of gettering at least a first gas or vapor and a second, different gas or vapor. The getter system also has a second, activated getter material capable of gettering the first, but not the second, gas or vapor. Finally, the getter system includes packaging for the first and second getter materials, such that the first and second getter materials may be placed together within a single compartment of the evacuated container and the second getter material will be more readily exposed to the first gas or vapor than the first getter material. In this manner, the first getter material will be protected from the first gas or vapor even though it is already activated.
