Abstract
A sample flow, including a plurality of components which have different types of spectra and are subjected to flocculation, is irradiated with a light of beam including two or more wavelengths. The transmitted light beam is received by a photoelectric converting device, and electric signals corresponding to respective wavelengths of the transmitted light beam are obtained. The correlation coefficient between the electric signal is calculated, from which the flocculation process of the sample flow with regard to the elapsed time can be easily and quickly detected.
