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

CLP ISM 01.2 and ILM 05.2 & 05.3 Standards for ICP-MS
For verification of inter-element and background correction factors at the beginning and the end of each analysis run. In addition, a verification must be done after every 20th sample. Two solutions are required for the most common interference check: Solution A, the interferents alone (CL-INT-A2) and Solution AB, a combination of interferents (CL-INT-A2) and analytes (CL-INT-B3 or CL-INT-B4). Solution A is prepared by diluting CL-INT-A2 10-fold. Solution AB is prepared by diluting CL-INT-A2 10-fold and CL-INT-B3 or CL- INT-B4 100-fold; for example, 10 ml of CL-INT-A2 and 1 ml of CL-INT-B3 or CL-INT-B4 into a 100 ml volumetric flask, brought to volume with a matrix blank. Once prepared, the solutions should be analyzed consecutively, starting with Solution A.
