NKMCX-150-3 Polymeric MCX SPE Cartridge, 150 mg/3 mL (CAT#: STEM-AL-0050-ZJF)

This product is a polymeric MCX SPE cartridge used for extraction and cleanup of basic analytes. It contains a mixed-mode sorbent combining strong cation exchange and reversed-phase retention. The sorbent base is highly cross-linked PS/DVB polymer with sulfonic acid functional groups. The retention mechanism allows basic compounds to interact through cation exchange and hydrophobic retention. The cartridge format supports preparation of samples from complex matrices before analysis. It is applicable to biological, food, and environmental samples containing pesticides, veterinary drug residues, drugs, or metabolites. The broad pH stability supports method development under different pH conditions. This model provides a 150 mg sorbent bed in a 3 mL cartridge format.
