Figure 5: Properties of hydrogen-water generated by an electrolysis apparatus. Note: (A) Dependency of mean bubble size on the electrolysis time was measured. Preparation method of the bath water was the same as that in [Figure 4]. (B) The relation between the number of nano-bubbles and the dissolved hydrogen concentration after 30 minutes (~150 μg/L), 60 minutes (~250 μg/L), and 120 minutes (~400 μg/L). (C) Dissolved oxygen concentration depending on the electrolysis time was measured. (D) Time course of the hydrogen nano-bubble concentration, and comparison of the instruments. Concentrations of hydrogen nano-bubbles were serially measured using the Lita Life Ver. 2 instrument and other instruments (made by A and B companies). Data are expressed as mean ± SD, and were analyzed by Student’s t-test.
