  • Patent number: 11022585
    Abstract: A plurality of chromatograms is run using a salt gradient with a range of constant pH values or using a pH gradient with a range of constant salt concentrations. A chromatography optimization algorithm can be used to identify at least one salt gradient chromatogram or at least one pH gradient chromatogram to establish optimized buffer conditions. The chromatography optimization algorithm can include a total number of peaks algorithm, a peak-to-valley algorithm, and/or a peak capacity algorithm.
    Type: Grant
    Filed: June 9, 2019
    Date of Patent: June 1, 2021
    Assignee: Dionex Corporation
    Inventors: Shanhua Lin Liehr, Jung Un Baek, Christopher A. Pohl, Mark Lee Tracy, Xiadong Liu
