Designed specifically for trace organics and analytic chemistry applications requiring low organics and bacteria, the CLiR 5200 delivers up to 2.5 LPM of Type I, 18.2 MΩ water quality on demand. The water is purified using a staged purification process which includes high-purity ion exchange resins to remove dissolved minerals, and ultraviolet light for bacteria sterilization and TOC reduction. As the water exits the system, a final filter removes particulates and bacteria to reach Type I water specifications. The CLiR 5200 uses a dual wave length technology to reduce organics and sterilize bacteria at the same time. Certain applications like HPLC and LC, require ultrapure water with TOC levels less than 5 ppb. The water is typically used in the preparation of mobile phase preparation, creating blanks, and sample dilution. For trace metals analysis, ICP-OES/ICP-MS require the organic and ionic purity for their dilution and dissolution processes. [Cartridges and final filter sold separately.]
