Product Description
Specifications
adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger..
Performance features and uses:
Molecular Sieve 4A is an alkali alumina 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). 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 dioxyde and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excluded.
Chemical Formula_/span>Na2O·AI2O3·2.0SiO2·4.5H2O.
