ENrich ion exchange chromatography columns are designed for high-resolution separation of proteins and other biomolecules at fast flow rates.

These chromatography columns contain either Q resin for separation by anion exchange or S resin for separation by cation exchange. Both resins have a particle size of 10 µm.

• The 1 ml ENrich columns can complete a high-resolution separation in about 20 minutes — Q resin (780-0001) and S resin (780-0021).
• ENrich columns are also available in an 8 ml configuration for larger sample loads and purification scale-up — Q resin (780-0003) and S resin (780-0023).
• The 1 ml and 8 ml columns operate at a maximum pressure of 500 psi

Features and Benefits of ENrich High-Resolution Ion Exchange Chromatography Columns

• Provide increased flow rate flexibility with various sample viscosities and temperature conditions
• Deliver superior quality, reproducible separations
• High capacity, even at high flow rates
• Stable at pH 2–12

Applications of ENrich High-Resolution Ion Exchange Chromatography Columns

For purifying biomolecules in a variety of workflows:

• Final polishing of antibodies
• Secondary purification after affinity/tag purification
• High-resolution separation of biomolecules
• Contaminant removal

The ion exchange columns are compatible with organic acids (1 M acetic acid), 8 M urea, 6 M guanidine HCl, chaotropic agents, detergents, salts, and 1 M NaOH. Alcohol, up to 20% (v/v), can be used to enhance the solubility of nucleotides and peptides.

This support is completely compatible with all commonly used aqueous buffers.
