Astra C18-Hybrid
Hybrid Silica – Where Nature Meets Innovation
Hybrid silica fuses the robustness of inorganic silica with the versatility of organic chemistry, creating a material engineered for superior performance. With enhanced durability and refined surface functionality, hybrid silica enables smarter, longerlasting solutions across advanced industrial and technological applications. High density end-capping together with fully hybrid particles synthetised from scratch deliver superior high alkaline durability compared to partially hybrid solutions.
KEY BENEFITS
- Fully hybrid particles for a wide pH range from 1 to 12
- C18 with improved selectivity for basic compounds
- Narrow peaks at low pH – significant reduction in acid hydrolysis of the C18 ligand
- Enhanced method development flexibility
- Double end-capping with unique surface treatment for superior peak shape
- Stability in 100% aqueous mobile phase, even at elevated pH
