NKMCX-500-3 Polymeric MCX SPE Cartridge, 500 mg/3 mL (CAT#: STEM-AL-0052-ZJF)

This product is a polymeric MCX SPE cartridge designed for solid phase extraction of basic analytes. It combines strong cation exchange chemistry with reversed-phase retention. The sorbent consists of highly cross-linked PS/DVB polymer bearing sulfonic acid functional groups. This configuration supports strong retention of basic compounds through dual interaction modes. The cartridge is used for sample cleanup, matrix reduction, and analyte enrichment. It is suitable for complex sample types including biological, food, and environmental matrices. The broad pH stability provides flexibility for sample preparation methods. This model provides a 500 mg sorbent bed in a 3 mL cartridge format for high sorbent loading in a compact cartridge.
