Abstract: PURPOSE:To perform accurate measurement without the effect of multiple scatterings by correcting the data with a correcting device by the amount corresponding to the concentration of sample particles, and computing the distribution of particle sizes for the sample particles with a particle-size distribution computing apparatus based on the corrected measured data. CONSTITUTION:The transmittance of single-wavelength light M is computed based on the ratio between the data of transmitted light which is measured with a photosensor 35 for transmitted light and the data of transmitted light for blank sample liquid corresponding to the above described data. By the same way, the transmittance of laser light L is computed based on the ratio between the data of transmitted light which is measured with a photosensor 38 for transmitted light and the data of the transmitted light for the corresponding blank sample liquid. The data measured with the photosensor of a ring- shaped detector 25 are increased and corrected by the amount corresponding to the transmittance obtained from the measured data of the photosensor 35 for transmission. The measured data from photosensors 26a, 26b... are corrected in correspondence with the transmittance obtained from the measured data from the sensor 38 in the same way.
