Regular columns for typical phase separation are packed with alumina or silica. Alkyl, aliphatic or phenyl bonded phases are usually used for reverse phase separation.
The choice of your partitioning medium is decided by the nature in the sample matrix as well as the properties with the analytes. In addition, the sample can be heated, have its pH modified, or be if not handled to help make the analytes more obtainable for the partitioning medium.
