The US EPA has approved Dionex's reagent-free ion chromatography systems with eluent regeneration as an alternative test procedure for methods 300.0 and 300.1. The methods cover compliance monitoring of drinking water.According to the Environmental Protection Agency (EPA) Office of Ground Water and Drinking Water's Technical Support Center, chromatographic systems that use eluent regeneration are acceptable for use in the original methods "as long as all original method quality control parameters are met." The EPA ruled that these methods are useful for drinking water compliance monitoring performed under National Primary Drinking Water Regulations.
