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 (CSHTM) Technology.
Advantages of CSH Technology include:
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.
