[Solved] how the Retention factor, Rf , value is determined

CONTENT:

Retention factor, or Rf value, is a key chromatographic statistic that describes how a molecule behaves in a chromatographic system. The calculation involves dividing the compound`s travel distance by the solvent front`s travel distance. The chromatogram is usually visualised using an appropriate detection technique, like UV absorption or fluorescence, to identify the spots corresponding to the chemicals of interest. This allows for the piecise calculation of the Rf value. After being located, the exact distances between the origin and the solvent front as well as between each location and the origin are measured. The Rf value, which provides important details regarding the relative affinity of the chemical, is obtained by dividing the distance travelled by the compound by the distance travelled by the solvent front. in comparison to the mobile phase, the stationary phase`s compound. This parameter facilitates the identification of compounds and permits the adjustment of chromatographic settings for the purposes of separation and analysis.
