Scope
This document describes the evaluation method of the particle size index of microbubbles in a microbubble dispersion system and the sampling method from the dispersion point in the microbubble generation or storage container to the detection point in the measuring device. This document is applicable to microbubbles (with or without shells) with a particle size range of 1 μm to 100 μm in water.
