Ion-Exchange SCX SPE Cartridge

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;
• 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.
