Rf values

• Chromatography is a technique for separating the components of a mixture
• The mobile phase in chromatography may be either a liquid or a gas, while the stationary phase is either a solid or a liquid.
• Chromatograms are produced in chromatography.
• The Rf value, or retention factor, is a ratio used to describe the distance a component in a mixture travels in relation to the distance the solvent travels.
• Equation for RF value

  distance moved by substance/distance moved by solvent front
