Ceramospher is coined from "ceramic" and "sphere." This is a completely new type of column for optical separation where the optically active metal complex Δ-Ru(phen)32+(phen=1,10-phenanthroline) is adsorbed to porous spherical ceramics by cation exchange. |

The clay mineral used for the chromatographic support has a multilayer structure. Analyte molecules are supposed to enter narrow gaps between the layers, and to fit into environments where three-dimensional interactions for chiral recognition take place. When trying many chiral compounds, probability of successful optical separation is much higher than those of conventional chiral columns. |

Difference between RU-1 and RU-2 |
RU-2 packing material is created from RU-1 by further special hydrophobic treatment. Consequently, Ceramospher (Chiral) RU-2 allows the use of aqueous (reversed phase) mobile phases. |
