EPA States Standards
Each US state has developed analytical protocols for dealing US federal regulations. Although there is a great deal of overlap among these methods, each states protocol takes their unique conditions and requirements into account.;Agilent has prepared a number of reference standards for a variety of state and federal protocols. Standards include state specific methods for underground storage tank (UST), petrochemical analysis, biodiesel fuels, and cannabinoids. 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 certificate showing the actual weight of each analyte is supplied with the standard.
