Thin layer chromatography (TLC) represents a commonly used technique for polarity measurement. However, current TLC analysis presents several problems, including the need for a large number of attempts to obtain suitable conditions, as well as irreproducibility due to non-standardization. Herein, we describe an automated experiment system for TLC analysis. This system is designed to conduct TLC analysis automatically, facilitating h","authors_text":"Dongxiao Zhang, Fanyang Mo, Hao Xu, Jianning Zhang, Jinglong Lin, Michael C.
