Chemxin Molecular Sieve type 5A is an alkali alumina silicate; it is the sodium form of the Type A crystal structure. 5A molecular sieve has

an effective pore opening of about 5 angstroms (0.5nm). our type 5A molecular sieve will adsorb most molecules with a kinetic diameter

of less than 4 angstroms and exclude those larger. Such adsorb-able molecules include simple gas molecules such as oxygen, nitrogen,

carbon dioxide and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excluded.
