Product Description
Features and Benefits

- Scalable from UHPLC to preparative chromatography
- Phases for small molecules and biomolecules
Additional Information
XBridge columns use ethylene-bridged hybrid particles in which organic bridges are incorporated into the inorganic backbone. This material architecture expands the usable pH range compared to conventional silica and enables robust methods even in the strongly alkaline range. The product family includes reverse-phase, shield, and phenyl-selective columns, as well as HILIC and amide-phase columns and wide-pore materials for peptides, proteins, glycans, and oligonucleotides. Identical chemistries across different particle sizes facilitate transfer between HPLC, UHPLC, and preparative formats.
