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.

Abstract: A continuous flow analyzing method and an apparatus for carrying out the analyzing method wherein a sample is injected in a continuously flowing carrier and the sample is introduced into a detector by the carrier to thereby perform a quantitative analysis contained in the sample. In the method the sample to be analyzed is filled into a sample introduction switchover valve (SISV); a portion of the sample from the SISV is injected into the carrier and an analysis of this sample is conducted to obtain a detection peak for the analyzed sample. These steps are repeated and the sample is continuously analyzed by, in the case where a detection peak obtained in the detector is under an optimum analysis range, increasing an injection amount of the sample, and in the case where the detection peak obtained in the detector is over the optimum range, decreasing the injection amount of the sample. Adjustment of the detection peak is repeated until the detection peak reaches the optimum analysis range.
