Bio IEX Ion Exchange Chromatography Columns
Ion Exchange (IEX) chromatography columns are packed with nonporous polymeric particles. Bio IEX-HPLC columns are designed for high resolution, high recovery and efficient separations of biological compounds, such as oligonucleotides, proteins, and peptides. Bio IEX columns are versatile for all types of biomolecules and are available in strong cation-exchange (SCX), weak cation-exchange (WCX), strong anion-exchange (SAX) and weak anion-exchange (WAX) phases. Speed and efficiency can be optimized for your needs with a variety of particle sizes. All phases are available in 1.7, 3, 5 and 10 μm non-porous particles sizes. PEEK-lined hardware is available for the 2.1 and 4.6 mm ID columns with the two larger particle sizes for compounds that are sensitive to metal. In addition, PEEK-lined hardware can mitigate corrosion that can occur with high salt.
Product Details
Features
- 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
- Wide pH and temperature range
