    • In controlling a sterile water production device, if pH of sterile water is smaller than a preset pH, an additional aqueous hypochlorite solution is injected into the sterile water to increase the pH back to the preset pH, and a molar quantity of residual alkaline impurities present in such additional aqueous hypochlorite solution is determined. Next, a predetermined amount of further additional aqueous hypochlorite solution is injected into the sterile water, wherein such predetermined amount is an amount required to yield additional content of hypochlorous acid in a resulting sterile water, to such a degree that a molar quantity of that hypochlorous acid is equal to the foregoing determined molar quantity of residual alkaline impurities. After such injection, pH of sterile water yielded is increased, and an acid aqueous solution is then injected into the sterile water to thereby decrease the increased pH back to the preset pH.
    • 在控制无菌水生产装置时,如果无菌水的pH小于预设的pH值,则将另外的次氯酸盐溶液注入无菌水中以将pH增加至预设的pH,并且存在碱性杂质的摩尔量 在这种另外的次氯酸盐水溶液中测定。 接下来,将预定量的另外的另外的次氯酸盐溶液注入到无菌水中,其中这样的预定量是在得到的无菌水中产生额外含量的次氯酸所需的量,使得该次氯酸盐的摩尔量 酸等于上述确定的残留碱性杂质的摩尔量。 在注射后,产生的无菌水的pH增加,然后将酸性水溶液注入无菌水中,从而将增加的pH降低至预设的pH。
