How to clean and dry the electrolytic cell of a Coulomb method microwater analyzer? 　　The electrolyte cell of the newly purchased Kuhn method micro moisture analyzer does not require cleaning. When the Karl Fischer reagent in use becomes ineffective [The specific signs indicating that the reagent has become ineffective are: ① It has been used for more than a month ； ②Darkening of the Karl Fischer reagent (in the absence of periodate) ； ③It is difficult to reach the end of the electrolysis process. When replacement is necessary, we recommend that you clean and dry the electrolytic cell: 　　Cleaning the electrolytic cell: When cleaning, please use reagents such as anhydrous ethanol or anhydrous methanol to clean all components of the electrolytic cell thoroughly (note: the electrolytic electrodes and measurement electrodes must never be cleaned with water, as this will cause measurement errors; also, do not clean the areas where the electrode leads are connected). 　　Drying of the electrolytic cell: Place it in an oven at approximately 60°C and dry it for 4 hours, then allow it to cool naturally.
