Abstract
A compressed gas cartridge is pierced and dispenses its pressurized gas through a permeation element that serves as a way to regulate the rate of gas dispensed out an outlet in the surrounding housing. It has been found that the use of a permeation element can control the rate of dispensation to an almost constant rate over time, which is valuable in applications such as art preservation for just one example.
