Copure® SCX SPE

Copure® SCX is a silica-based strong cation exchanger. Its pheylsulfonic acid ligand engenders strong cation exchange capacity, while the benzene ring gives rise to additional non-polar interactions. SCX is able to extract positively charged basic compounds such as amines. Features: Low pKa, enabling strong interaction with basic compounds Electrical charge of sulfonic acid changeable by adjusting pH of eluent, ensuing convenient eluting Specifications: Surface area: 510 m2/g
