Abstract
The present invention presents a particle-size distribution measuring apparatus which allows measuring simultaneously the dispersion state of particles in suspension medium and the particle-size distribution of the particles. The present invention is a particle-size distribution measuring apparatus which measures the particle-size distribution of particles included in a sample. The particle-size distribution measuring apparatus comprises a pH meter for measuring the pH value of the sample and an information processing portion which determines the relation between the pH value and the particle-size distribution on the basis that the pH value measured by the pH meter and the measured particle-size distribution are in the same state.

A particle-size distribution measuring apparatus to measure particle-size distribution of particles in a sample, comprising:
- a pH meter measuring the pH value of the sample;
- and
- an information processing portion coupled to the pH meter, the information processing portion determining the relation between the pH value and the particle-size distribution;
- wherein the relation is based on the pH value measured by the pH meter being in the same state as the measured particle-size distribution.
A method for controlling the dispersion state of a sample having particles, comprising:
- simultaneously monitoring the pH value and particle-size distribution of the sample;
- determining the relation between the pH value and the particle-size distribution on the basis that the measured pH value and measured particle-size distribution are in a same state;
- determining the optimal pH value to maintain the particle-size distribution at a desired particle-size distribution.
