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
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 (INT-A1) and Solution AB, a combination of interferents (INT-A1) and analytes (INT-B3). Solution A is prepared by diluting INT-A1 20-fold. Solution AB is prepared by diluting INT-A1 20-fold and INT-B3 100-fold; for example, 5 ml of INT-A1 and 1 ml of INT-B3 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.

CLP ISM 01.2 & ILM 05.3 Standards for ICP
For ILM 05.3, a standard must be run at the Contract Required Detection Limits (CRDL). To verify linearity near the CRQL, this standard is analyzed at the beginning of the analysis run, after the ICV/ICB and before the ICSA and ICSAB. In addition, this standard must be run at a frequency of not less than 20 analytical samples and at the end of the analysis run, followed by the ICSA/ISCAB. The sequence order is CCV, CCB, CRI, ICSA, ICSAB, CCV, and CCB. For ISM 01.2, at least one of your calibration standards must be at the Contract Required Detection Limit (CRDL). This standard, when diluted, can be used as a calibration standard to fulfill this requirement.
