Ultra fine bubble measurement system, measuring method and temperature regulator for ultra fine bubble measurement system

摘要

Problem to be solved: to provide an ultra fine bubble measurement method and a measuring system capable of discriminating between ultra fine bubbles and solid particles having the same diameter at atmospheric pressure such as atmospheric pressure.Solution: the temperature regulator 100 is frozen to a solid phase by freezing the solution to be measured and decompressed to obtain a liquid phase.The measuring instrument 200 executes a first measurement for measuring the number of particles having a particle size of 1. Mu. M or less in the measured solution before freezing, and a second measurement for measuring the number of particles having a particle size of less than 1. Mu. M in the solution to be measured after the thawing.The calculating part 300 executes an operation for obtaining the number of particles of the ultra fine bubble in the measured solution from the difference in the number of particles having a particle size of 1. Mu. M or less in the measured solution measured by the first measurement and the second measurement.Diagram
