The Waters family of Protein-Pak high-resolution ion-exchange (IEX) columns are suited for analyzing intact biomolecules, including monoclonal antibodies, recombinant proteins, DNA/RNA and vaccine components. The columns comprise one anion-exchange-quaternary ammonium-column chemistry and two cation-exchange column chemistries—a carboxy methyl and sulfopropyl—each contained on monodisperse, non-porous particles. The multi-layered network of ion-exchange functional groups on the particles result in high sample-loading capacities for proteins not found with use of typical non-porous particle IEX offerings. IEX 4.6- x 100-mm columns are suited for use on the ACQUITY UPLC system, which is optimized for maximum sensitivity, component resolution, and speed. Each column features ACQUITY UPLC eCord technology for monitoring critical individual column-use parameters.

Slow and Steady Wins the RaceIn the 100 years since Marie Curie won the Nobel Prize in Chemistry, women have made leaps and bounds in science and engineering. Following the extreme example of Madame Curie, women have exponentially raised their position in S&E in the last few decades. In a field previously (and traditionally) dominated by men, women seem to be slowly but surely taking over—or at least leveling the playing field. ...continue
