NKMCX-2000-12 Polymeric MCX SPE Cartridge, 2000 mg/12 mL (CAT#: STEM-AL-0058-ZJF)

This product is a polymeric MCX SPE cartridge intended for high-capacity extraction of basic analytes. It uses mixed-mode strong cation exchange and reversed-phase retention. The sorbent base is highly cross-linked PS/DVB polymer with sulfonic acid functional groups. Basic compounds are retained by a combination of ionic and hydrophobic interactions. The cartridge format supports cleanup and enrichment of complex samples before analysis. It is suitable for biological, food, and environmental matrices where basic target analytes are present. The polymeric sorbent is stable across a broad pH range and compatible with common organic solvents. This model provides a 2000 mg sorbent bed in a 12 mL cartridge format.
