Abstract
In 2010, we succeeded in measuring the sizes of bubbles generated by our GALF (GAs Liquid Foam) bubble generating system, using particle tracking analysis for the first time, and quantitatively confirmed the generation and presence of ultrafine bubbles measuring around 100 to 200 nm in diameter. After that, we also developed a new technology to generate a high density of ultrafine bubbles and launched our ultrafine bubble generating system (ultrafineGALF) in 2011. This report details several independent measurements of bubbles generated in water by ultrafineGALF, using dynamic light scattering, laser diffraction scattering, particle tracking analysis, and the electrical sensing zone method. It was found that the presence of ultrafine bubbles with a diameter of about 100 to 200 nm could be determined quantitatively using any of these methods.
