4 Sepax SFC-SCX Phase Structure Si Si Si Technical Specifications Silica: Spherical, high purity (< ppm metals) Pore size: Å Particle size:.8,.,,, m Pore volume:. ml/g Surface area: m /g Phase structure: Polymeric and mixed mode % Carbon:.% Coverage:. mol/m Description Sepax SFC-SCX is a silica based mixed-mode strong cation exchange phase. Its phase has a mixed chemical structure of sulfonic acid and phenyl group. This mixed mode of strong cation-exchange and hydrophobicity offers high selectivity and high resolution separation for cationic/basic and nitrogen containing compounds as well as desirable retention for a variety of weak cationic and neutral organic compounds. A uniform, polymeric bonding of Sepax SFC- SCX enhances its stability under various separation conditions. Sepax SFC-SCX has expanded its applications from the traditional SCX separation of cationic and nitrogen containing compounds to weak cationic and neutral organic molecules. Examples include separation of analytes of amines and polyamines, such as alkaloids, peptides, codeine, cough and cold ingredients. S H Highly controlled chemistry of polymeric monolayer formation and end-capping Mixed chemical structure of sulfonic acid and phenyl group Mixed-mode of ion-exchange and hydrophobic interaction enabling high selectivity and appropriate retention for a variety of compounds Polymeric bonding and end-capping to achieve the exceptionally high stability ph stability:.-8.
