Molecular sieve 4A is an alkali metal aluminosilicate with sodium form of type A crystal structure.
Molecular sieve 4A has an effective pore opening of about 4 angstroms (0.4nm). It will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger. Such adsorbable molecules include simple gas molecules such as oxygen, nitrogen, carbon dioxide and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excluded.
