Bio IEX: High-res, charge-based analytical separations
Agilent Bio Ion Exchange HPLC columns are packed with polymeric, nonporous, ion exchange particles. Bio Ion Exchange Columns are designed for high resolution, high recovery and highly efficient separations of peptides, oligonucleotides and proteins. The Bio IEX family offers strong cation exchange (SCX), weak cation exchange (WCX), strong anion exchange (SAX) and weak anion exchange (WAX) phases. All Bio Ion Exchange phases are available in 1.7, 3, 5 and 10 µm non-porous particles sizes.
- Highly crosslinked and rigid nonporous poly(styrene divinylbenzene) (PS/DVB) particles are grafted with a hydrophilic, polymeric layer, eliminating nonspecific binding
- Uniform, densely packed ion exchange functional groups are chemically bonded to the hydrophilic layer (multiple ion exchange groups per anchoring) to increase column capacity
- Particles, coating and bonding are resistant to high pressures, promoting higher resolution and faster separations
- Multiple ion-exchange groups are captured on one anchoring to increase capacity
