PURPOSE:To enable an analysis to be automatically performed and obtain correct informations of numerous kinds at the same time by deciding the numerous characters of a fine particle to be measured at the same time by a signal discriminating circuit. CONSTITUTION:The measured value of the size of a particle detected by a detecting sensor 1, after digitized by a preamplifier 2, a peak hold 3 and an A/D converter 4 and temporarily stored (5), is discriminated by a signal discriminating circuit 6 and fed to a corresponding gate 26. On the other hand, the value of fluorescent intensity measured at the same time, after similarly digitized, passes the gate 26 for the corresponding particle size and every group classified by the particle size is stored in a data memory 27, being expressed as a histogram. Thus, the fine particle or the aggregate of fine particles can be automatically analyzed and correct informations of numerous kinds can be obtained at the same time.
