Torrance, Calif. – Phenomenex Inc., a global leader in the research and manufacture of advanced technologies for the separation sciences, introduces Yarra 1.8µm SEC-X300 – a high-resolution gel filtration (GFC)/aqueous size-exclusion (SEC) column for the separation of high molecular weight (HMW) biomolecules on HPLC and UHPLC systems. With a wide separation range of 10K to 700KDa and high efficiency, SEC-X300 is ideal for separating and characterizing monoclonal antibody (mAb) aggregates, antibody drug conjugates (ADCs) and biosimilars in drug discovery and development research. The HMW focus of the SEC-X300 complements the low molecular weight range (1K-450KDa) of the existing Yarra 1.8µm SEC-X150 column, providing two versatile separation tools for biopharmaceutical research. The proprietary Yarra surface chemistry, combined with bio-inert column hardware, reduces sample adsorption compared to other GFC/SEC columns currently on the market, providing improved recovery and more accurate quantitation of biomol
