Analysis Note
Loss on ignition (950 °C): ≤ 10 %
Water absorption capacity (24 hrs.,80 % relative humidity): ≥ 15 %
Application
- in desiccators and drying tubes
- for keeping absolute solvents dry
- for drying gases or solvents in drying columns
- for selective adsorption
Features and Benefits
- Easy to use: practically chemically inert, non-toxic, no disposal problems, dried liquids can be decanted
- High adsorption capacity even with a low water content of the substance to be dried
- High adsorption capacity even at high temperatures
- High adsorption affinity for polar and unsaturated organic molecules (however, H2O is always preferentially adsorbed)
- Selective adsorption: only molecules that can pass through the pores are adsorbed
