However, traditional column chromatography methods pose significant challenges in terms of efficiency and time, as they often rely on trial-and-error processes and accumulated experience. Even seasoned researchers often spend considerable time experimenting to identify optimal chromatographic conditions, a process typically marked by inefficiency and time consumption.  \nIn recent years, the rapid advancement of Artificial Intelligence (AI) in the field of chemical analysis and process optimization[2–4] has opened up new possibilities for improving traditional methods. Machine learning and data-driven modeling have shown great potential in the recognition of complex biological samples[5, 6] and drug development[7, 8] . These technologies are beginning to transform traditional workflows. Chemists have increasingly turned to advanced techniques, including machine learning and deep learning, to uncover patterns and regularities in complex data, leading to new perspectives and breakthroughs in chemical research[9–11] . In our group, we utilize machine learning methods in thin-layer chromatography(TLC)[12, 13] and highperformance liquid chromatography(HPLC)[14] to predict the relationship between corresponding chemical structures and their chromatographic retention values.  \nFrom the perspective of a data-driven research paradigm, machine learning leverages datasets composed of a significant amount of data. However, despite the fact that column chromatography has been developed for many years[1], researchers often view it as a tool without systematically collecting experimental conditions and parameters related to the process. Chromatographic datasets often have a large number of missing values and low standardisation, which can pose a challenge for further statistic research, even if some
