Analysis of disinfection byproducts, including nine haloacetic acids, bromate, and dalapon using IC–MS/MS per US EPA Method 557

Clean drinking water is critically important to human health. Typically, both mechanical and chemical processes are needed to ensure drinking water quality; however, the by-products of chemical processes can include chlorinated to halogenated acids (HAAs) and bromate among others. Because excessive consumption of these compounds can result in severe health issues, drinking water regulations require determination of the concentrations of disinfection by-products (DBPs) prior to release to the public. Thermo Fisher Scientific shows that quantitation of target DBPs in drinking water per U.S. EPA Method 557 is robust, reliable, reproducible, and requires no sample preparation, allowing significant time, hazardous waste, and cost savings.
