What Are RF Values?


The Rf value is the ratio of the distance shifted by the solute and the distance moved by the solvent (referred to as the Solvent front) alongside the paper where both distances are calculated from the ordinary source or application baseline. An application baseline is the place where the model is originally spotted on the paper.
Q&A Related to "What Are RF Values"
Short Answer: It's how far something moves compared to the solution that is carrying it. Long Answer: Rf is the "Retardation Factor", which is the ratio of the distance
1. Place the paper chromatogram flat on a table and trace the position of the "solvent front" with a pencil. The solvent front represents the distance traveled by the solvent

The distance travelled by a given component divided by the distance travelled by the solvent front. For a given system at a known temperature, it is a characteristic of the component

RF value is the distance travelled by a given component divided by the distance travelled by the solvent front. An RF value is known as retention factor. Rf values are used for identification because one can compare Rf values of the unknown sample with Rf Values of known compounds.
RF (retention factor) value is the number that tells you how long it will take for a substance to be dissolved by a given solvent. RF value is important in chromatography.
In chromatology, RF-values are a measurement based on the relative distance traveled by a sample of a substance in a procedure. Under standard conditions, it is a characteristic property of the substance.
