ICP-MS Contract Required Detection Limit Standard, SPEX CertiPrep
Standards Cationic Standards Multi-Element Standards

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 SPEX Certiprep laboratories, is your stamp of assurance. Instruments are calibrated with traceable reference materials and show you the actual found value of the solution you receive, not just an ideal, calculated number. 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 ILM 02.0 & 05.2 Standards for ICP and CLP-M/6020/SW-846 Standards for ICP-MS
A standard must be run at two times the Contract Required Detection Limits (CRDL), or at two times the Instrument Detection Limits (IDL), whichever is greater. This standardization is performed at the start and the end of each sample analysis or at least twice in each eight hour shift. All elements to be analyzed must be run except Al, Ba, Ca, Fe, K, Mg, and Na.


The CRDL-1 and CL-CRDL-1standards contain all of the required elements on the TAL, in their appropriate concentration ratios. CRDL-1 should be diluted by a factor of 1,000 prior to use in the “two times CRDL” run for ICP-AES analysis. For analysis by atomic absorption, CRDL-1 should be diluted by a factor of 2,000 prior to use in the “one time CRDL” run. CL-CRDL-1 should be diluted by a factor of 1,000 prior to use in the “two times CL-CRDL” run for ICP analysis. For analysis by atomic absorption, CL-CRDL-1 should be diluted by a factor of 2,000 prior to use in the “one time CL-CRDL” run."
