These are high-efficiency, silica-based columns, manufactured by bonding a specially designed proprietary ligand with both hydrophobic and weak cation-exchange properties. Selectivity of ionisable and neutral compounds can be controlled independently or simultaneously by tuning mobile phase ionic strength, pH or organic modifier.

• Adjustable selectivity
• Selectivity complementary to RP columns
• Ideal selectivity for separating basic molecules
• Multimode separation mechanism: RP, cation-exchange, ion-exclusion and HILIC
• Capable of separating a mixture of neutral and basic compounds
