Diffusion process characterizes the volume capacity. The volume capacity refers to the total volume of impurities that the getter can hold before it must be replaced. Volume capacity determines the getter lifetime.
Different impurities have different volume capacities, i.e. getter is more efficient at removing some impurities than others
Total amount of impurities that the getter material can hold is a function of the:
