By Product Type

DuPont™ AmberChrom™ chromatography resins are macroporous polymer resins designed for reverse phase chromatography of small molecules, peptides, and oligonucleotides. With a broad operating range and good chemical resistance to cleaning procedures, these polymeric reverse phase resins are excellent alternatives to reverse phase silica resins and give consistent performance cycle after cycle. Resins are available in a range of options to fit diversified requirements for purity, resolution, and throughput in manufacturing processes, giving end-users flexibility to design purification processes suited to their individual needs. These resins were developed for use in chromatography columns and can be used as bulk resin in batch adsorption mode as well. AmberChrom™ chromatography resins are supported by an appropriate quality and regulatory program. Regulatory support packages are available upon request and under confidentiality.

DuPont™ AmberChrom™  fine mesh ion exchange resins are a line of gel based strong acid cation and strong base anion resins available in varied with varied crosslinking’s and particle sizes.  Unlike ground, irregularly shaped particles, the AmberChrom™ ion exchange resins are spherical beads that allow for better process flow dynamics, column packing efficiency, and ease of handling.  Fine mesh ion exchange resins have faster kinetics as compared to convention larger sized ion exchange resin types, and can be easily scaled for meeting manufacturing needs.

DuPont™ AmberLite™ XAD polymeric adsorbents are macroporous hydrophobic resins (crosslinked DVB) that adsorb products or impurities. Like the other polymeric chromatography resins in the DuPont™ portfolio, these resins have high crosslinking levels that offer excellent mechanical and chemical resistance, leading to robust performance in customers’ purification processes, whether column processes or stirred-tank adsorption systems. Such resins are suitable for single use applications or these resin may be regenerated for multiple uses. Products are available in a range of particle sizes, pore sizes, and surface areas to provide a variety of adsorption capacity and selectivity.

DuPont™ AmberChrom™ chromatography resins are available in prepacked columns for people who prefer the convenience of ready-to-use columns for their benchtop research and analytical needs.
