Xselect Phenyl-Hexyl

XSelect™ HPLC columns are the next evolutionary step in Waters LC column technology. Based on Charged Surface Hybrid (CSH™) Technology, this HPLC column family offers the widest range of selectivity choices and superior peak shape improvements for basic compounds when operated in acidic, low ionic strength mobile phases (e.g., 0.1% formic acid).   XSelect OBD™ Prep columns offer extremely high mass loading under low ionic strength acidic conditions and raise the performance bar for lab-scale isolation and purification columns.

Responding to input received at many customer forums, Waters has developed the next evolution of particle technology: Charged Surface Hybrid (CSH^TM) Technology.

Advantages of CSH Technology include:

• Superior peak shape for basic compounds
• Increased loading capacity
• Rapid column equilibration after changing mobile-phase pH
• Improved batch-to-batch reproducibility
• Excellent stability at low pH

XSelect CSH Phenyl-Hexyl columns provide you with alternative analyte selectivity compared to traditional reversed-phase columns and are a valuable tool for method development. The trifunctionally bonded C6 phenyl-ligand is a robust, low bleed sorbent that selectively retains polyaromatic compounds through pi-pi interactions.
