WebFeb 22, 2024 · What are 3 factors that can affect Rf values in TLC? Rf values and reproducibility can be affected by a number of different factors such as layer thickness, … WebHigh Rf values from TLC using a nonpolar solvent means the pigment is more nonpolar. Lower Rf values mean the pigment is more polar. Draw or tape your TLC strip and label as many pigments as you can (see the next page for more information on pigments). Record the Rf values of each pigment next to its label.
