A substance that promotes dissolution of inorganic salts is added to provide the organic solvent with sufficient electric conductivity for electrical particle measurement. Such substances include either or both: Compound (a): a zwitterionic compound or compounds, and Compound (b): a compound or compounds including a hydroxyl group and a carboxyl or an amino group in the same molecule.
