  4A molecular sieve
Specification or purity: 60-80 mesh, dedicated for gas and liquid chromatography columns
Molecular formula: Na2O · Al2O3 · 2SiO2 · 9/2H2O
The pore size of 4A molecular sieve is about 4 angstroms, which is mainly suitable for drying gases and liquids. It can adsorb H2O, NH3, H2S, CO2, SO2, CO, chloroform, bromomethane, acetylene, ethane, ethylene, propylene, etc. Widely used for drying associated gas and natural gas in oil fields. It is also widely used for dehydration of ethanol. Also used for anti condensation of vacuum glass and other materials.
