NKMCX-2000-30 Polymeric MCX SPE Cartridge, 2000 mg/30 mL (CAT#: STEM-AL-0060-ZJF)

This product is a polymeric MCX SPE cartridge for extraction and cleanup of basic analytes. It combines mixed-mode strong cation exchange retention with reversed-phase retention. The sorbent is based on highly cross-linked PS/DVB polymer carrying sulfonic acid functional groups. The retention mechanism allows basic compounds to interact through charge-based and hydrophobic pathways. The cartridge format supports sample preparation before analytical measurement. It is suitable for complex biological, food, and environmental matrices containing basic analytes. The broad pH stability and solvent compatibility support flexible SPE method conditions. This model provides 2000 mg of sorbent in a 30 mL cartridge format for larger-volume sample preparation.
