description PROBLEM TO BE SOLVED: To provide a dispersion analysis method and device which enables the quantitative analysis of the state of aggregate, and to provide a dispersion stability evaluating method and device which enables the quantitative analysis of the stability of the dispersion. SOLUTION: The dispersion analysis method is used for analysis of the dispersion using a sample solution prepared by forming the aggregate of a dispersoid in a dispersing medium and contains a dispersing stage for dispersing the dispersoid forming the aggregate in the dispersing medium and a measuring stage for measuring the amount of the dispersoid dispersed by the dispersing stage. The dispersion analysis device includes a speaker 21 for propagating a sonic wave from the outside of a sample solution 14, a spectrophotometer 22 for measuring the absorbance of the sample solution 14 and a computer 23 for controlling the speaker 21 and the spectrophotometer 22. The absorbance measured by the spectrophotometer 22 is the measured value of the amount of the dispersoid and, in the stability evaluating device of the dispersion, the stability of the dispersion is evaluated on the basis of the measured value of the spectrophotometer 22.
