NKMCX-30-3 Polymeric MCX SPE Cartridge, 30 mg/3 mL (CAT#: STEM-AL-0047-ZJF)

This product is a polymeric MCX SPE cartridge for mixed-mode extraction of basic analytes. It combines strong cation exchange chemistry with reversed-phase retention in a single sorbent bed. The sorbent is made from highly cross-linked PS/DVB polymer functionalized with sulfonic acid groups. This configuration enables retention through charge-based interaction and hydrophobic interaction. The cartridge is used for cleanup and enrichment of analytes from complex matrices. It is applicable to biological, food, and environmental samples containing basic target compounds. The pH-stable polymeric structure supports use across a broad range of method conditions. This model provides 30 mg of sorbent in a 3 mL cartridge format for low-bed-mass SPE processing.
