The Rf index, or retention factor, is a value used in chromatography to describe the relative distance traveled by a compound compared to the solvent front. It is calculated by dividing the distance traveled by the compound by the distance traveled by the solvent. Rf values typically range from 0 to 1, with higher values indicating greater mobility of the compound in the stationary phase. This index is useful for identifying and comparing substances in a mixture based on their separation characteristics.
