Top 12 Types of Chromatographic Techniques | Biochemistry

As in most other forms of chromatography, paper chromatography uses R n values to help identify compounds. R f values are calculated by dividing the distance the pigment travels up the paper by the distance the solvent travels (the solvent front). Because R f values are standard for a given compound, known R n values can be used to aid in the identification of an unknown substance in an ...
