PURPOSE:To measure the same sample on the best condition for the detection of respective necessary pieces of light information by irradiating a sample flow with laser beams which differ in shape and kind by using plural irradiation luminous flux systems. CONSTITUTION:Two irradiation luminous flux systems 8 and 9 are provided and a laser beam from a light source is converged to illuminate different positions A and B of the sample flow. Photodetection systems 10 and 11 are provided corresponding to the laser beam irradiated positions A and B. Scattered light generated at the position A is measured and fluorescent light generated at the position B is measured. The time difference between both measurements corresponds to the time that the sample flow requires to flow between the points A and B. A signal fetch/arithmetic processing part 16 for the fluorescent light is operated a specific time after the peak of the scattered light to integrate fluorescent light pulses. Consequently, both pieces of light information on the same sample are measured while made to correspond to each other accurately.
