In planar chromatography in particular, the retardation factor (''R''f) is defined as the ratio of the distance traveled by the center of a spot to the distance traveled by the solvent front. Ideally, the values for ''RF'' are equivalent to the R values used in column chromatography.〔 Although the term retention factor is sometimes used synonymously with retardation factor (''R''f), in regard to planar chromatography, the term is not defined in this context. 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, which is inversely proportional to the retardation factor. ==General definition== In chromatography the retardation factor, ''R'', is the fraction of the sample in the mobile phase at equilibrium, defined as:〔 :$\backslash \; R\; =\; \backslash frac\}$ 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Retardation factor」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
