Product Description

Molecular Sieve 4A is an alkali alumino silicate, it is the sodium form of the type A crystal structure.

Molecular Sieve 4A has an effective pore opening of about 4 angstroms, it will adsorb most molecule wiyh a kinetic diameter of less than 4 angstroms and exclude those larger. Such adsorbable molecule include simple gas molecules such as oxygen, nitrogen, carbon dioxide and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics excluded.
