Most dissolved inorganics are either positively or negatively charged and can transmit an electrical current when electrodes are inserted in the water. The more ions that are present, the greater the conductivity, or the lower the resistivity of the water sample. About Labconco Careers Contact Us. Live Help Chat. Media Articles Infographics Videos.

The water should be filtered first to remove organic material, and additional filtering with a reverse osmosis RO system will remove a significant number of additional contaminants. This leaves only a small amount of ionized minerals for the DI system to remove. Water distillation, on the other hand, can remove more impurities than just ions.
This process removes nearly all minerals, many chemicals, and most bacteria. That doesn't mean that it removes everything, however, especially if the water contains volatile organics and certain other contaminants. These impurities will evaporate and stay in the distilled water. As with deionized water, pre-treatment filtering is an important step. Since both treatment methods produce high purity water, choosing between deionized water vs.
Distilled water is often more pure, especially if it's been filtered first, and it should not contain any bacteria or other pathogens which could, in theory, be left in DI water. Distilled water, especially if it's been double or triple distilled, can be used for nearly all laboratory applications, including those in which DI water might not be pure enough.

That said, deionized water is a good option for many uses, including cooling applications, many laboratory uses, pharmaceutical industries, and more. It involves a deionization process that uses high purity resin to initiate an exchange cycle, cleansing the water of unwanted ions.
However, the configuration of equipment for this process varies widely depending on several factors. Deionized water is a true water blank, meaning it assumes the chemistry of whatever product is added to it. This has critical implications, especially for the medical industry. When medical product manufacturers create a product, water is almost always mixed in. That way, when the saline formula is added to the water, it creates an exact replica of the solution they need.
If the water contains any impurities or metal, such as copper or lead, it will cause adverse health effects for whoever injects the product.
