Efficiency of the quantitative bridge for coloring matter has already been reported. For the determination of colorless substances, it is recommended that a developer which makes the Rf value of the substance to be near 1 be used and to use coloring matter whose Rf value is the same as that of the sample under the same conditions. The position of the sample is calculated from the relationship between the solvent front and the quantitative bridge.
