WebJul 18, 2024 · This difference is due to the relative affinities of analytes with stationary and mobile solvents. The more the relative affinity with a stationary phase an analyte has, the more it will stay in place, and the lesser the Rf value will get and vice versa. Rf value is the characteristic identification value for analytes at given temperatures. WebThe value of retention factor depends upon the affinity of solute towards stationary phase and mobile phase. More the affinity, lesser the value and vice versa. It is a unitless quantity. Retention Factor is determined by various properties such as thickness layer of stationary phase, moisture, saturation of solvent, sample size etc.
