The formula is: R f = Migration distance of the protein. Migration distance of the dye front. To work out the R f value by hand (rather than using software), follow these simple steps: 1.
WebCalculate Rf values. Using the chromatogram, Rf values can be calculated with the equation distance moved by substance / distance moved by solvent. As seen earlier, the distance moved by substance is the distance from the start line to the centre of the spot. Worked example: Look at the chromatogram in the diagram above. WebSep 7, 2024 · To calculate an Rf value, divide the distance travelled by the component – in other words, the distance from the starting pencil line to the coloured spot -by the distance travelled by the solvent. Rf values are important because each component has a fixed Rf value under a specific set of conditions.
