Ion exchange and hydrophobic chains are bonded onto the surface of silica providing unique selectivity.
Initially compounds that possess basic functionality are retained by ion exchange functionality. A washing step with an appropriate pH removes ionizable impurities. Passing an organic solvent through the column will then remove retained impurities that result from hydrophobic bonding.
