NKMCX-500-6 Polymeric MCX SPE Cartridge, 500 mg/6 mL (CAT#: STEM-AL-0055-ZJF)

This product is a polymeric MCX SPE cartridge for solid phase extraction of basic compounds. It uses a mixed-mode sorbent that combines strong cation exchange and reversed-phase retention. The sorbent is made from highly cross-linked PS/DVB polymer with sulfonic acid functional groups. This chemistry supports retention of basic analytes through ionic and hydrophobic interactions. The cartridge is intended for cleanup and concentration of analytes from complex sample matrices. It is suitable for biological, food, and environmental sample preparation workflows. The sorbent remains stable across a broad pH range and is compatible with common organic solvents. This model provides 500 mg of sorbent in a 6 mL cartridge format for higher-capacity SPE processing.
