NKMCX-100-3 Polymeric MCX SPE Cartridge, 100 mg/3 mL (CAT#: STEM-AL-0049-ZJF)

This product is a polymeric MCX SPE cartridge for sample preparation of basic analytes. It combines strong cation exchange retention with reversed-phase retention in a mixed-mode sorbent. The sorbent is based on highly cross-linked PS/DVB polymer and contains sulfonic acid functional groups. This design supports retention of basic compounds through ionic and hydrophobic interactions. The cartridge is used to prepare samples before instrumental analysis by removing matrix components and enriching target compounds. It is suitable for biological, food, and environmental sample matrices. The sorbent maintains stability across a broad pH range. This model provides 100 mg of MCX sorbent in a 3 mL cartridge format.
