Ion chromatography (IC) is a well-established technique for monitoring inorganic anions in environmental waters around the world. It is approved by the U.S. Environmental Protection Agency (U.S. EPA) for compliance monitoring of primary and secondary inorganic anions in drinking water and has been validated by European standards organizations, including the International Standards Organization (ISO). These agencies have published IC methods for the analysis of inorganic anions in drinking water, groundwater, and wastewater. These methods can be made faster and more cost-effective, however, by using the latest IC technologies, including high-pressure IC.
In this summary, we will discuss regulatory compliance testing of municipal drinking water and wastewater, and how this testing can be made faster and more cost-efficient through the use of high-pressure-capable ion chromatography systems.
