4A Molecular Sieve Gas Chromatography Statio
4A Molecular Sieve Gas Chromatography Statio
Name: chromatographic statio
Specifications: 4Å molecular sieve, 100-120 mesh
The pore size of 4A molecular sieve is 4A. It can adsorb water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, and propylene. It does not adsorb any molecule (including propane) with a diameter larger than 4A. It is one of the most widely used molecular sieves in industry.
Chemical formula: Na2O·Al2O3·2SiO2·9/2H2O
Si-Al ratio: SiO2/Al2O3≈2
Effective Pore Size: a
