Product Description
Features and Benefits
- CSH and HSS particle platforms
- Wide selectivity range for method development
- Good peak shapes for basic analytes
- High retention on HSS phases
- Scalable between HPLC and UHPLC
Additional Notes
XSelect combines two deliberately different particle platforms. CSH uses a BEH hybrid framework with a controlled positive surface charge and is specifically designed to provide good peak shapes and increased loading capacity for basic compounds. HSS is based on high-strength silica and often provides stronger retention as well as different selectivities than BEH or CSH phases. C18, phenyl-hexyl, fluoro-phenyl, T3, PFP, and cyano offer a broad range of method development options; specialized peptide phases extend these concepts to bioanalytical separations.
