Abstract
A combination moisture and hydrogen getter comprises PA1 (a) a moisture getter comprising a readily oxidizable metal; and PA1 (b) a hydrogen getter comprising (i) a solid acetylenic compound and (ii) a hydrogenation catalyst. A method of scavenging moisture from a closed container uses the combination moisture and hydrogen getter to irreversibly chemically reduce the moisture and chemically bind the resultant hydrogen.
