These methods are based on gel filtration chromatography, also called molecular sieve chromatography, which is a form of size-exclusion chromatography.
32.
The method, while popular in many laboratories, is inferior in terms of safety and drying effectiveness relative to molecular sieves.
33.
For oxygen, molecular sieve is used, for nitrogen a zeolite, for carbon dioxide and water a zeolite or activated carbon.
34.
Other common desiccants include activated charcoal, calcium sulfate ( Drierite ), calcium chloride, and molecular sieves ( typically, zeolites ).

The company has around 30 years of experience in the production and development of Carbon Molecular Sieves and has customers worldwide.

3?molecular sieves are used to dry a range of materials, such as ethanol, air, refrigerants, natural gas and unsaturated hydrocarbons.
37.
5?molecular sieves are stored at room temperature, with a relative humidity less than 90 % in cardboard barrels or carton packaging.
