Extracting basic compounds


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.



  • Low pKa, enabling strong interaction with basic compounds
  • Electrical charge of sulfonic acid changeable by adjusting pH of eluent, ensuing convenient eluting



Surface area: 510 m2/g
Particle size: 40 - 75 μm
Pore size: 70 Å



  • Determination of residual pesticides / veterinary drugs in foodstuff, such as macrolides
  • Determination of illicit drugs, such as amphetamine
  • Analysis of drugs and drug metabolites in biological matrices
