Proficiency Testing Schemes, Calibration Standards & Reagents
Water Pollution
Matrices with high concentrations of analytes for testing water pollution or wastewater. Standards are based on requirementsof the United States Environmental Protection Agency Clean Water Act and may be used to satisfy PT requirements worldwide.
Soil
Matrices designed to fulfill requirements for monitoring soil and solid matrices. Dried and homogenized standards of soil and sewage sludge designed to meet the United States Resource Conservation and Recovery Act and may be used to satisfy PT requirements worldwide.
Radiochemistry
Matrices in soil, vegetation, air filters, and water for monitoring of radiochemicals.
Calibration Standards
A variety of inorganic standards including metals, anions, pH, and other common inorganics that can be used for primary calibration or to prepare second source calibration standards.
Water Supply
Matrices with low concentrations of analytes for testing water supply, drinking water, or ground water. Standards are based on requirements of the United States Environmental Protection Agency Safe Drinking Water Act and may be used to satisfy PT requirements worldwide.
Underground Storage Tank (UST)
ERA’s Underground Storage Tank (UST) products in water and soil matrices are purposefully designed to meet accreditation requirements for Petroleum Hydrocarbons analysis in various jurisdictions.
Low-Level CRMs
Matrices with low concentrations of analytes for testing water supply, drinking water, water pollution, wastewater, or ground water.
Reagents
High purity reagents for environmental analysis intended for laboratory and industrial procedures. Production lot volumes available from 0.5 L – 1000 L.
Microbiology
Matrices with low and high concentrations of analytes for testing bacteria in drinking water and wastewater. Samples are delivered as lyophilized pellets in a glass vial with phosphate buffer dilution blank.
Air & Emissions
Matrices consisting of organic, inorganic, and particulate matter for testing emissions and ambient air. Standards are designed to meet regulations of the United States Environmental Protection Clean Air Act and may be used to satisfy PT requirements worldwide.
Custom Standards
Standards manufactured to unique specifications available with a range of analytes, concentrations, and matrices.
