Analytical Applications of Thin Layer Chromatography Linh Nguyen Santa Barbara City College Abstract. For the purpose of this lab, thin layer chromatography (TLC) is used to analyze and identify the twenty different amino acids that are commonly used in the synthesis of proteins. Based on the data that is obtained from the experiment, we have concluded that the molecular compounds’ polarity can determine their migration rates over the TLC plate. As a result, while hydrophobic molecules have strong
