Method for determining life of at least one chromatography column

A computer-implemented method (140) for determining the lifetime of at least one chromatography column (116) of at least one chromatography device (110) is disclosed, wherein the method (140) comprises the steps of: i) receiving model input chromatography data via at least one communication interface (128); ii) determining, using at least one processing device (130), at least one state variable indicative of the lifetime of the chromatography column (116) based on the model input chromatography data using at least one data-driven model; iii) evaluating the determined state variable by using the processing device (130), thereby determining information about the life, where the evaluating comprises comparing the determined state variable with at least one threshold value. Furthermore, a test system (112), a computer program and a method for operating a chromatography column (116) are disclosed. 本发明公开了一种用于确定至少一个色谱装置(110)的至少一个色谱柱(116)的寿命的计算机实现方法(140)，其中所述方法(140)包括以下步骤：i)经由至少一个通信接口(128)接收模型输入色谱数据；ii)使用至少一个处理装置(130
