  • Patent number: 8568586
    Abstract: The present invention provides automated systems and methods for monitoring column performance in process chromatography, and applications thereof. In an embodiment, column performance is monitored by generating a plurality of process values such as, for example, conductivity values or pH values with a detector during a chromatography step transition between a first mobile phase liquid and a second mobile phase liquid. The process values are transformed to form transformed process values in which noise present in the process values is suppressed. Column performance parameters are calculated based on the transformed process values and displayed during movement of the second mobile phase liquid through the chromatography column.
    Type: Grant

  • Patent number: 8410928
    Abstract: Methods and systems for evaluating and/or monitoring chromatography column performance are provided. Embodiments apply multivariate analysis (MVA) methods to process data as well as transition analysis data to provide a comprehensive evaluation of chromatography column performance. In embodiments, transition analysis data generated over extended periods of time can be analyzed together with process data to evaluate column performance. Further, embodiments enable a compact and robust tool for combining and presenting performance evaluation results, which allows for time-efficient performance examination.
