4? molecular sieve packed column
4? molecular sieve packed column Details:

Name: Packed column
Specification: 1m*3mm
Model: 4?

The 4? molecular sieve has a pore size of 4?, and it adsorbs water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, and propylene. It does not adsorb any molecules (including propane) with a diameter greater than 4A. The selective adsorption performance of water is higher than any other molecules. It is one of the most used molecular sieve varieties in industry.

Chemical formula: Na2O·Al2O3·2SiO2·9/2H2O
Silicon to aluminum ratio: SiO2/Al2O3≈2
Effective pore size: about 4?
