4A molecular sieve chromatography

The molecular sieve 4A, 4A molecular sieve, Na2O, Al2O3, 2SiO2, 4.54A molecular sieve pore size ofabout4, which is mainly suitable for gas, liquid drying. Can be adsorbed NH3, H2O, H2S, CO2, SO2, CO, methyl chloride, methyl bromide, acetylene, ethane, ethylene, propylene, etc.. Widely used in oil field gas, natural gas and other dry. Is also widely used for ethanol dehydration.Also used for anti condensation vacuum glass etc..

Gas chromatographic carrier
