CSH (Charged Surface Hybrid) Technology
The Charged Surface Hybrid (CSH) particle is Waters third generation hybrid particle technology. Based on Waters Ethylene Bridged Hybrid (BEH) particle technology, CSH particles incorporate a low-level surface charge that improves sample loadability and peak asymmetry in low-ionic-strength mobile phases, while maintaining the mechanical and chemical stability inherent in the BEH particle technology.
The advantages of CSH columns include:
- Superior peak shape for basic compounds
- Increased loading capacity
- Rapid column equilibration after changing mobile-phase pH
- Improved batch-to-batch reproducibility
- Exceptional stability at low and high pH
- Seamless transfer between HPLC and UPLC technology platforms
- Available Particle Sizes: 1.7, 2.5, 3.5, 5, and 10 µm
- Column Chemistries: C18, Phenyl-Hexyl, Fluoro-Phenyl
