WebOct 10, 2013 · We learned how to calculate the RF value, also known as the retention factor or retardation factor, and how you would report that when presenting in a lab report or in the literature. We showed … WebThe RF value calculator is a tool used in chromatography to calculate the retention factor or RF value of a compound. The retention factor is a measure of how strongly a compound interacts with the stationary phase in a chromatography system. It is defined as the ratio of the distance traveled by the solute (DSU) to the distance traveled by the ...

WebMar 9, 2024 · Calculating RF RF= Distance moved by compound / Distance moved by solvent For the purple spot in figure 3b (the textbook diagram), the RFis 0.8. For the same spot in figure 3a (typical student results), what is the distance moved by the spot? Where would you draw the line? There will be a very large error in any value calculated. WebThe R f value is calculated as follows: If the R f value of one of the components of the mixture equals the R f value of one of the standard reference materials then that component is know to be that reference material. Note that because the solvent always travels at least as far as the highest dye, the R f value is always between 0 and 1. WebAug 11, 2024 · A convenient way for chemists to report the results of a TLC plate in lab notebooks is through a " retention factor ", 2 or R f value, which quantitates a compound's movement (Equation 2.3C.1 ).
