SPEX CertiPrep CLP Methods(5% HNO3 Matrix)

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.

US EPA SOW ILM 05.3/ISM 01.2 gives specific procedures for the methods of analysis, target elements, and concentration levels. 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

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.

Chemicals sold by Cole-Parmer are not intended for and should not be (i) used for medical, surgical or other patient oriented applications, or (ii) combined with any food product or ingested in any form.

This multi-element standard contains 21 elements.
