High Performance Chiral Columns for Enantiomer Separation

On SUMICHIRAL OA columns, direct separation of various enantiomers can be realized effectively and efficiently. Enantiomeric separation is achieved via the various diastereomeric interactions such as hydrogen bonding, charge transfer, and host-guest interactions. SUMICHIRAL OA columns are useful for accurate determination of optical purity and prep chromatography of pure enantiomers for biologically active compounds such as pharmaceuticals, pesticides, and perfumes.
