Strong Cation Exchange Mixed-Mode SPE for Basic AnalytesThe CleanX MCX SPE Cartridges feature a polymeric strong cation exchange (SCX) sorbent with a mixed-mode retention mechanism, designed for superior extraction and cleanup of basic analytes from complex biological matrices.Engineered to operate across a wide pH range (0–14), CleanX MCX integrates ion-exchange and reversed-phase (RP) interactions, delivering powerful selectivity, reproducibility, and recovery for both polar and non-polar compounds.This dual-mode chemistry makes CleanX MCX an ideal choice for bioanalytical laboratories, clinical research, and pharmaceutical testing where precision and purity are critical.
