Abstract
A thin-layer chromatography plate and a thin-layer chromatography uses a thin-layer chromatography plate that has a first separating agent layer, which has the same optical response as the sample, and a second separating agent layer, which is disposed adjacent thereto and has an optical response that is different from the aforementioned optical response; carries out development of the sample in the first separating agent layer; thereafter carries out further development of the spots from the first separating agent layer toward the second separating agent layer; and detects the spots in the second separating agent layer through exposure to ultraviolet radiation or a color-development treatment with a coloring agent.
