Nexera UC columns are specifically designed for SFC, resulting in optimum bonding coverage, ligand density, and all factors
leading to high capacity phases which exhibit excellent selectivity and peak shape. The Napthyl phase exhibits strong pi-pi and charge transfer interactions for both aromatic and non-polar compounds. The rigid naphthalene molecule also enables the shape selectivity needed for many diastereomeric separations. These unique properties place its selectivity between graphitized carbon and alkyl type stationary phases. Development of the separation on a Nexera UC Basic analytical column is highly recommended before purchasing a prep column. Prep columns cannot be returned once used.
