WebAs soon as the DI water comes out of the system and is exposed to the atmosphere, it dramatically loses resistivity as it quickly becomes ionized again. It is also true that it will lose resistivity the moment that it comes in contact with any container due to contaminants inherent in the bottle. WebDeionized water, also referred to as DI water or grade 1, is water that has been purified of virtually of its mineral ions through the use of uniquely manufactured ion-exchange filters in accordance with ASTM D1193. In some cases, this method may be used in combination with reverse osmosis (RO) to raise the level of purity.
