  • Publication number: 20230028051
    Abstract: The present invention relates to a liquid chromatography system configured to operate with at least one column and configured for purification of a sample comprising a target product using a predefined process. The liquid chromatography system comprises a controller configured to: control the operation of the chromatography system to run the predefined process; retrieve column data accessible from a data storage, the column data being specific to each column; and adapt at least one process parameter of the predefined process for each column based on column data. Whereby the predefined process is adapted to each column to obtain the target product and maintain the performance of the liquid chromatography system.

  • Publication number: 20220163493
    Abstract: Disclosed is a chromatography system arranged to perform automated chromatography column efficiency testing for a specific column to determine efficiency parameters such as h and As and optionally to further provide guidance to the user with respect to column efficiency, the system having a controller arranged to automatically access data to enable the calculation of a column compression plate height, said data being derived from at least stored parameters of the specific column and the resin to be used in that column, thereby to calculate the efficiency of the column.
