Description

Description of Strong Cation Exchange (SCX) Solid Phase Extraction (SPE) Cartridges

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

Features of Strong Cation Exchange (SCX) Solid Phase Extraction (SPE) Cartridges

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

Detection of pesticides and antibiotic residues in foods, such as macrolides
Detection of drug abuse, such as amphetamine
Analysis of drugs and their metabolites in biological matrices
