Abstract
A method of preserving an oxygen sensitive item is disclosed. The method involves injecting at least 0.15 gram of an inert gas into a container comprising the oxygen sensitive item and oxygen, without raising a pressure within the container above 10 psig, to form a barrier layer of the inert gas between the oxygen sensitive item and the oxygen in the container without displacing all of the oxygen from the container.
