These CRMs were produced and certified from naturally contaminated matrices and have not been fortified or modified in any way. Analytical data for Certification was obtained using USEPA SW846, 3rd edition methods 3050 (hot block) and 3051 (microwave) using nitric acid extraction. Analysis was carried out according to USEPA methods 6010 (ICP-EOS), 6020 (ICP-MS) and 7000 (AES).
The samples are intended for use in analytical systems using these and related methods. Note that nitric acid extraction in not as regorous as aqua regia, and these samples may not be suitable for method validation where an aqua regia extraction is used.
