Discover how CSH Technology redefines UPLC and HPLC column performance
CSH Technology columns offer chromatographers the widest range of selectivities and greater performance in LC/MS-compatible mobile phases. Our patent-pending, Charged Surface Hybrid (CSH(tm)) Technology powers the new ACQUITY UPLC CSH and XSelect HPLC columns and provides:
• Widest selectivity range: CSH C18, CSH Fluoro-Phenyl, CSH Phenyl-Hexyl chemistries
• Sharper peak shapes for ionized compounds
• Seamless transferability
• Higher peak capacities
• Rapid equilibration after mobile-phase pH changes
