    The R f (retardation factor) value is the ratio of the solute’s distance travelled to the solvent’s distance travelled. The word comes from chromatography when it was discovered that a given component will always travel the same distance in a given solvent under the same conditions.

    The Rf value is a ratio, and it represents the relative distance the spot traveled compared to the distance it could have traveled if it moved with the solvent front. An Rf of 0.55 means the spot moved 55% as far as the solvent front, or a little more than halfway.

    18 de jul. de 2022 · What are the units for Rf values? Rf values are unitless as the ratio of similar quantities is always just a number. The solute migration value is compared by the solvent front migration value to calculate the Rf value which gives just a ratio number.

    24 de feb. de 2024 · The calculation of RF values involves a straightforward formula: RF value = distance traveled by the compound / distance traveled by the solvent front. This formula encapsulates the essence of RF values, providing a quantitative measure of a compound's movement relative to the solvent front.

    The Rf value of a compound is equal to the distance traveled by the compound divided by the distance traveled by the solvent front (both measured from the origin). For example, if a particular compound travels 1.5 cm and the solvent front travels 6.0 cm, then the compound's Rf value is 0.25. .

    The Rf value is a dimensionless number that ranges from 0 to 1. It is calculated by dividing the distance traveled by the compound by the distance traveled by the solvent front. The resulting Rf value represents the relative mobility of the compound in the chromatogram.

    Retardation factor. In chromatography, the retardation factor ( R) is the fraction of an analyte in the mobile phase of a chromatographic system. [1] In planar chromatography in particular, the retardation factor RF is defined as the ratio of the distance traveled by the center of a spot to the distance traveled by the solvent front. [2]
