Description of SCX SPE Cartridge

Strong cation exchange(SCX) SPE cartridge is a silica-based benzenesulfonic acid-based filler. Its negatively charged sulfonic acid group has a strong cation exchange capacity, and the benzene ring has certain hydrophobic retention. SCX extracts positively charged basic compounds such as amines.

Features

  • Lower pKa.
  • Strong cation exchange and reversed double retention;
  • SCX cartridges are particularly useful for the isolation of positively charged molecules, such as peptides, proteins, amino acids, and other charged species.
  • The binding capacity of SCX SPE cartridges depends on factors like sample pH, ionic strength, and the specific resin used.
  • By adjusting the pH value, the charged state of the sulfonic acid group can be changed to facilitate elution.

Application of SCX Cartridge

  • Detection of drug abuse, such as amphetamine;
  • Analysis of drugs and their metabolites in biological matrices;
  • Detection of pesticides and antibiotic residues in foods, such as macrolides.
  • Used for the purification and concentration of proteins and peptides with cationic charges, aiding in proteomic studies and mass spectrometry analysis.
  • Isolate and purify cationic drug compounds and metabolites from biological samples for pharmaceutical analysis.
  • Extract and preconcentrate cationic contaminants, such as heavy metal ions, from water and soil samples.
  • Separate and analyze cationic compounds like amino acids and certain additives in food and beverages.
