Planar chromatography is a separation technique in which the stationary phase is present as or on a plane. ... The specific Retention factor (R f) ...
The separation factor is one distribution ratio divided by another; it is a measure of the ability of the system to separate two solutes. For instance, if the distribution ratio for nickel (D Ni) is 10 and the distribution ratio for silver (D Ag) is 100, then the silver/nickel separation factor (SF Ag/Ni) is equal to D Ag /D Ni = SF Ag/Ni = 10.
Separation factor (alpha) is a relative comparison on how well two neighboring components of the mixture were separated (i.e., two neighboring bands on a chromatogram). This factor is defined in terms of a ratio of the retention factors of a pair of neighboring chromatogram peaks, and may also be corrected for by the void volume of the column.
Resolution (chromatography) ... In chromatography, resolution is a measure of the separation of two peaks of different retention time t in a chromatogram. [1] [2] [3] [4]

The Purnell equation is an equation used in analytical chemistry to calculate the resolution R s between two peaks in a chromatogram. [1] [2]= (′ + ′) where R s is the resolution between the two peaks
The fundamental resolution equation is used in chromatography to help relate ... term is the thermodynamic factor, and the [k 2 '/(1+k 2 ')] term is the retention ...
The distribution constant (or partition ratio) (K D) is the equilibrium constant for the distribution of an analyte in two immiscible solvents. [1] [2] [3]In chromatography, for a particular solvent, it is equal to the ratio of its molar concentration in the stationary phase to its molar concentration in the mobile phase, also approximating the ratio of the solubility of the solvent in each phase.
