4A Molecular Sieve is sodium form of aluminosilicate .The adsorption of different molecules by 4A depends upon the major factors like molecular diameter and polarity of adsorbate and effective pore diameter of 4A. The Molecular Sieve will adsorb molecules which have a critical diameter less than four angstrom (CO2,H2O & NH3)
