Meeting regulations in any industry, standards are essential for periodically checking the accuracy of equipment pieces. By comparing against the known values, output readings detect errors present and inform personnel adjustments are required. Once the settings of the manual or automatic instruments have returned to zero, the reestablished conditions will yield optimal working performance. Calibrating with concentrated standards eliminates the possibility that environmental changes will induce instrumental miscalculation when accuracy matters most.

ICP-MS Spike Sample 4, SPEX CertiPrep
Supplier: SPEX CERTIPREP LLC
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 Standards for ICP-MS
Our spike standard, CL-SPIKE-4, provides all of the analytes required for the ICP-MS and the AA spike. Add 1 ml of CL-SPIKE-4 to aqueous samples and 2 ml of CL-SPIKE-4 to solid samples prior to digestion.
