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.
- Excellent peak symmetry
- Exceptional stability from pH 1 to 10
- Reduced need for mobile-phase modifiers
- Long column life
C8(EC) is double-bonded before fully endcapped using a unique proprietary end-capping reagent. It is less prone to acid hydrolysis than trimethylsilane, which provides freedom
from residual silanols and enhanced stability under low-pH operating conditions. The bonding is monomeric. Genesis® C8(EC) columns exhibit superior stability at alkaline pH.
