Safeguard our most precious resource with quality water-testing reference materials

To ensure water quality—and protect human health—regulatory agencies have established guidelines for monitoring contaminant levels in drinking water, groundwater, and wastewater. Successfully complying with these guidelines depends upon the accreditation of your reference material supplier. Agilent ULTRA chemical standards are tested and manufactured using rigorous quality management processes, including ISO 17025 and ISO 17034.
