The Avantor® ACE® Excel® C18-AR phase utilizes a specially developed ligand combining a C18 chain with integral phenyl functionality, thus combining the benefits of both C18 and phenyl characteristics into a single phase. This can be used for 'standard' C18 column separations but is additionally recommended for separations that involve compounds containing aromatic functionality.
