<P>PROBLEM TO BE SOLVED: To provide an analyzer capable of easily evaluating grain size dispersibility. <P>SOLUTION: An electric field spatially-regularly arranged is applied to particles movably dispersed in a medium to migrate particles. The resulting density distribution of the particles generates a diffraction grating, and in the annihilation process of the diffraction grating through the stop or modulation of the application of the electric field, intensity of diffracted light from the diffraction grating is measured to obtain the size of particles. In the above measurement method, using of the square root or natural logarithm of the measured value of the diffracted light intensity for the analysis allows the dispersibility of the particle size to be evaluated with high convergence by using the least squares method even in the case of particles of dispersive diameter or the case where particles to be measured include particles of different sizes. <P>COPYRIGHT: (C)2012,JPO&INPIT |
