Molecular Sieve 4A
Molecular Sieve type 4A is an alkali alumino silicate; it is the sodium form of the Type A crystal structure.
4A molecular sieve has an effective pore opening of about 4 angstroms (0.4nm). Type 4A molecular
sieve 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.
