EPA 600 Series Standards
The 600 series methods are designed for monitoring organic pollutants in industrial and municipal discharges under the United States Clean Water Act (see 40 CFR 136.1). Agilent has prepared a series of reference standards for the 600 series methods, as well as the necessary surrogate and internal standards. Each component in a reference standard is pre-analyzed, with most analytes being >99% pure, and the solvents are of the highest quality available. All solutions are gravimetrically prepared to a precision of ± 2.0%. A Level II ISO Guide 34 Reference Material Certificate of Analysis is available for each product.
