CHEM 2219: Exp. #1 Thin Layer Chromatography (TLC)
WebAn RF value will always be in the range 0 to 1; if the substance moves, it can only move in the direction of the solvent flow, and cannot move faster than the solvent. For example, if particular substance in an unknown mixture travels 2.5 cm and the solvent front travels 5.0 cm, the retardation factor would be 0.50. WebThe Rf (rate of flow) value is usually constant under fixed conditions such as TLC plate, developing solvent, and temperature. Therefore, each compound can be identified based … WebThin-layer chromatography (TLC) is a useful technique for identifying compounds, determining their purity and following the progress of a reaction. One of the main advantages of TLC is that it only requires ...
