Common use of Analytical Procedures Clause in Contracts

Analytical Procedures. For each measurement parameter, reference the applicable standard analytical procedure(s) or provide a written description of the analytical procedure(s) to be used. Provide performance information for each analytical procedure in terms of accuracy, precision and detection limits. Method performance information should meet or exceed the Quality Assurance objectives identified in element number 5. For the sake of convenience, all or part of elements number 8, 9, 10, 11, and 13 may be incorporated into this element. The choice of when to reference a manual's test procedure and when to document a complete Standard Operating Procedure (SOP) can only be made on a case-by-case basis. It has been observed that few laboratories, external to the Contract Laboratory Program (CLP), follow exactly, all important details of a standard reference method. Other times standard reference methods provide or allow options (example - the use of different gas chromatography columns for polychlorinated biphenyl (PCB) determinations). Reference to analytical methods in the United States Environmental Protection Agency (EPA) Publications, the American Society for Testing and Materials (ASTM) or "Standard Methods" can be appropriate; however, required sample preparation procedures (filtration, digestion, etc.) also need to be referenced. For example, the United States Environmental Protection Agency’s “Methods for Chemical Analysis of Water and Wastes" provides three (3) different test procedures for most metal determinations and at least four (4) sample preparation protocols for each metal. Each combination of metal determination and sample preparation exhibits different degrees of accuracy, precision, and sensitivity of measurement. Different quality control audits are used for each combination of metal determination and sample preparation. The exact combination used for each metal must be specified.
