4A Molecular Sieve Mesh, Beaded

CHEMICAL FORMULA Na12[(AlO2)12(SiO2)12] • nH2O

PRODUCT DESCRIPTION
mSORB 4A molecular sieve is an alkali alumino-silicate in the spherical form. It is the sodium form of the Type A crystal structure with pore diameters of approximately 4 angstroms. The 4Å molecular sieve will adsorb molecules such as oxygen, nitrogen, carbon dioxide and straight chain hydrocarbons. Aromatics and branched chain hydrocarbons will not be adsorbed.
