MOLECULAR SIEVE 4A

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)
