Next-Generation HPLC Degassing

    When analytical scientists review their HPLC laboratory set-ups, they typically have a couple goals in mind.

    1. How can we enhance the performance of the system and produce repeatable, certifiable results?
    2. What methods could we implement to increase the efficiency of the system?

    To work through these goals, an often overlooked but key element to consider is the degasser.

    The Background of Degassing

    To maintain the stability of the HPLC system flow rate and mobile phase composition, a degasser plays the sole role in reducing the amount of dissolved air in the mobile phase and the stability of the entire HPLC system. Today’s HPLC systems have 2 potential mobile phase mixing arrangements. In the first scenario, solvents are mixed before they enter the pump. In the second scenario, mobile phase mixing occurs after the pump but before the injection valve. Both scenarios will help avoid chromatographic errors if the HPLC system incorporates an efficient, in-line vacuum degasser for the mobile phase mixture and its components.

    Analytical instrument manufacturers should consider:

    • Improving the user experience by integrating the degasser into the HPLC system control software for intelligent control of the vacuum
    • Utilizing bioinert materials that are compatible with a broad range of solvents, supporting a wide range of method applications
    • Lower flow restriction
    • Smaller instrument footprint
    • High performing, efficient solution
    • And many more
