However, in column chromatography, the retention factor or capacity factor (k) is defined as the ratio of time an analyte is retained in the stationary phase to the time it is retained in the mobile phase, [3] which is inversely proportional to the retardation factor.
Retention distance, or R D, is a concept in thin layer chromatography, ... are the Retention factor of the compounds sorted in non-descending order, R f0 = 0 and R f ...
Example chromatogram showing signal as a function of retention time. In chromatography, resolution is a measure of the separation of two peaks of different retention time t in a chromatogram. [1] [2] [3] [4]
They are analogous to the calculation of retention factor for a paper chromatography separation, but describes how well HPLC separates a mixture into two or more components that are detected as peaks (bands) on a chromatogram. The HPLC parameters are the: efficiency factor(N), the retention factor (kappa prime), and the separation factor (alpha ...
Chromatography, pronounced / ˌ k r oʊ m ə ˈ t ɒ ɡ r ə f i /, is derived from Greek χρῶμα chrōma, which means "color", and γράφειν gráphein, which means "to write".". The combination of these two terms was directly inherited from the invention of the technique first used to separate biological pigme

The retention factor (R ƒ) may be defined as the ratio of the distance travelled by the solute to the distance travelled by the solvent. It is used in chromatography to quantify the amount of retardation of a sample in a stationary phase relative to a mobile phase. [2] R ƒ values are usually expressed as a fraction of two decimal places.
The retardation factor (R f), or retention factor, quantifies the results. It is the distance traveled by a given substance divided by the distance traveled by the mobile phase. [citation needed] Development of a TLC plate. Spots that appear purple separate into red spots and blue spots.
