Web21 aug. 2024 · How to Calculate Rf Values for TLC? Rf value is the relative distance traveled by a particular compound with respect to the mobile phase. Rf value for TLC.. The Rf value is the retention factor used in the identification of organic compounds in a mixture. The Rf value is calculated by measuring the relative distance traveled by a particular ... WebStep Two: Preparation of the TLC plate. Plate one will be used to identify an unknown solution by comparing the distance it travels on the TLC plate to the distance traveled by the stock solutions. On plate two you will be running the remaining unknown solutions, and will be used for identification of the unknown by calculation of the Rf factors.
