ABSTRACT:
The present invention provides an apparatus for measuring particle distribution for determining particle size distribution with higher precision by compensating for a reduction in scattering light due to the color of a sample and due to the particle size characterized by Mie scattering theory, and a method for measuring particle size distribution using such an apparatus. The apparatus for measuring particle distribution irradiates a laser beam to be measured, converts the resulting scattering light into an electrical detection signal, and performs inverse operation processes on the detection signal to calculate the particle size distribution of the sample. The measuring apparatus is provided with a laser light source that variably changes the wavelength of the laser beam depending on samples. The measuring apparatus is further provided with a particle size distribution analysis section for calculating the particle size distribution of the sample by using scattering light from the sample that are obtained upon application of the laser beam having a wavelength that allows measurement of the strongest from scattering light the sample.
