Genesis® columns use a new generation adsorbent based on high-purity metal-free 120Å spherical silica. Particle size offering includes 3, 4, 7, and 15μm. Genesis® columns exhibit excellent peak symmetry and exceptional pH stability from 1 to 10.

Genesis® AQ Reversed Phase
  • Designed for separating hydrophilic and polar compounds
  • Stable retention times in 100% aqueous mobile phases
  • Rapid equilibration
  • Unique reversed-phase selectivity
The Genesis® AQ adsorbent employs an optimum ratio of C18, short (non-TMS) chains, and polar surface groups bonded to high-purity 120Å silica to allow rapid equilibration and provide consistent, reproducible chromatography with stable retention times in 100% aqueous eluents.

Retention on Genesis® AQ is greater for polar analytes but lower for non-polar compounds compared to Genesis® C18. Uracil, which is typically an unretained peak on C18 columns, is well retained on the Genesis® AQ adsorbent. Acids and bases exhibit good peak shapes. Although Genesis® AQ excels with water-rich mobile phases, it can also be used in gradient and isocratic modes with a full spectrum of mobile phases.
