CLP Standards for ICP & ICP-MS Our Contract Laboratory Program (CLP) standards allow you to Calibrate with Confidence®. The standards are to be used in conjunction with the Statement of Work for Inorganic Analysis; Multi-Media/Multi-Concentration Document Number ILM 05.3/ISM 01.2. The final ICP check, performed in our own laboratories, is your stamp of assurance. We calibrate our instruments with traceable reference materials and show you the actual found value of the solution you receive, not just an ideal, calculated number as so many other standards manufacturers do. The combination of elements, concentrations and matrices listed have been diagnosed by SPEX CertiPrep for convenience of use and stability. US EPA SOW ILM 05.3/ISM 01.2 gives specific procedures for the methods of analysis, target elements, and concentrationlevels. Standards are specified not only by the elements present and their relative concentrations, but also the order and frequency of running standards, blanks and samples. Details of these specifications may be found in the US EPA SOW ILM 05.3/ISM 01.2 in the following sections: • Exhibit C, Inorganic Target Analyte List (TAL) • Exhibit D, Analytical Methods • Exhibit E, QA/QC Requirements Alternate Standards We also provide a solution of alternate interferents and alternate analysis. Alternate interferents A (INT-A2) and alternate analytes B (INT-B2) may be prepared in combination with the INT-A1 and INT-B3 solutions mentioned, or any combination involving the four solutions, depending on the analytes and interferents of interest to you. We provides ICP-MS interferents and interferent check solutions for SW-845.
