ABSTRACT:
A method of continuous flow analysis is provided which enables a plurality of color-forming components contained in a sample to be simultaneously analyzed with utmost ease. The method involves irradiating the sample with a measuring light which generates a wavelength having absorption bands with respect to such color-forming components, measuring the absorbance of each of the components in a color-formed state while the components are being adjusted stepwise in their color-forming state, and comparing the resultant absorbances of the components with each other. Preferably, a plurality of measuring cells are used to stepwise adjust the sample in its color-forming state, the measuring cells being connected in tandem such that a color former and/or a masking agent are incorporated in the sample while the latter is being caused to successively flow through these cells so that the sample is adjusted in its color-forming state at each of the measuring cells and measured in respect of its absorbances.
