Key Features:
1. Ultra-Pure Silica Matrix
High Purity: Utilizes ultra-pure fully porous spherical silica, minimizing metal ion content and ensuring excellent peak symmetry for acidic and basic compounds.
2. Proprietary Bonding Technology
Stable Chemistry: Features a unique bonding process with aminopropyl silane, creating a stable stationary phase that delivers reproducible results.
3. Superior Equilibration Speed
Time-Saving: Reaches equilibrium much faster than traditional bare silica columns, significantly reducing method development time and startup wait periods.
4. Robust Water Tolerance
Versatile: Unlike bare silica columns, which are highly sensitive to water content, the AY-G-NH2 demonstrates excellent stability even with varying water concentrations in the mobile phase. This makes it ideal for HILIC applications using aqueous-organic gradients.
