Ultrapure Water Testing

Ultrapure water (also known as UPW) — is water that has been treated to the highest levels of purity for all contaminant types. There are rigid standards concerned about the quality & purity of the ultrapure water used in research and development laboratories (such as preparation of sample, reagent, media and solutions), food and beverage industry (such as production of baby formula, dairy products, soft drinks, and beer), semiconductor processing (such as cleaning and rinsing of semiconductors and printed circuit boards), chemical industry (such as chemical synthesis, production, and quality control) and pharmaceutical manufacturing (such as formulation, blending, washing and dissolving various compounds). Since contaminants in water can affect the accuracy of analytical results and the efficacy, stability and safety of final products, water validation and testing are extremely important for life science service companies.
