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.

CLP ILM 05.3 Standards for ICP-MS
Our spike standard, CL-SPIKE-4, provides all of the analytes required for the ICP-MS.

Gentamicin Sulfate, Reference Standard

Gentamicin Sulfate, Reference Standard

Supplier: USP

USP Reference Standards are specified for use in conducting official USP–NF tests and assays. USP also provides Reference Standards specified in the Food Chemicals Codex as well as authentic substances—high-quality chemical samples—as a service to analytical, clinical, pharmaceutical and research laboratories. To confirm accuracy and reproducibility, USP Reference Standards are rigorously tested and evaluated by multiple independent laboratories including USP, commercial, regulatory, and academic labs. USP also provide publicly available, official documentary standards for pharmaceutical ingredients in the USP–NF that link directly with our primary reference standards.

• Exhibit C, Inorganic Target Analyte List (TAL)
• Exhibit D, Analytical Methods
• Exhibit E, QA/QC Requirements

Initial Calibration Verification for CLP Methods
The US EPA retains analytical services through the Contract Laboratory Program (CLP). The CLP follows detailed SOPs derived from EPA methods. The CLP methods require calibration of analytical instrumentation whithin the expected quantitative range (ICAL standards) and additional CLP QA standards (ICV standards) to verify the calibration curve at each of the selected wavelengths that wil be used for sample analysis.

Our verification standards contain all of the elements on the TAL list and are independent standards for testing an instruments calibration curve. SPEX CertiPrep's ICV standards are designed to be used with their corresponding instrument calibration standards (ICAL).

We recommend dilution of ICV standards to a range within your instruments calibration curve. A dilution of 20-fold is recommended.
