Analytical Procedures Sample Clauses

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.

Analytical Procedures. Instrumental Neutron Activation Analysis (INAA) The weighed sample (generally 10 to 40 g) is irradiated epithermally for 20 minutes in a neutron flux with an approximate density of 1 x 1011 neutrons/cm2/second. Counting begins seven days after irradiation. The counting time is somewhat variable (6 to 11 minutes) and is matrix dependent. Counting is done on a germanium- lithium co-axial counter. The counting data is accumulated on a VAX computer and is subsequently converted to concentrations. Numerous international reference samples are irradiated with each batch of routine samples.Elements determined by INA analyses include: Na, Sc, Cr, Fe, Co, Ni, Zn, As, Se, Br, Rb, Zr, Mo, Ag, Cd, Sn, Sb, Te, Cs, Ba, La, Ce, ▇▇, Eu, Tb, Yb, Lu, Hf, Ta, W, Ir, Au, Th, and U. The sample weight is also reported. Data for Zn, Se, Zr, Ag, Cd, Sn, Te, and Ir are not published because of inadequate detection limits and/or precision.

Analytical Procedures. The internal auditor should apply analytical procedures as the risk assessment procedures at the planning and overall review stages of the internal audit. It involves various comparisons as depicted below: In determining the extent to which the analytical procedures should be used, the internal auditor should consider the following factors:

Analytical Procedures. (a) Analytical Procedures applicable to the Goods have been provided by the Company to the Suppliers and/or are attached hereto. The Supplier acknowledges having received the Analytical Procedures and agrees to comply fully therewith. (b) In the event Analytical Procedure apply to the Purchase Order, the Supplier warrants and undertakes that pursuant to such Analytical Procedures: (i) the Supplier has tested no fewer than 3 samples of bulk material which will comprise the Goods; (ii) all samples are fully and unconditionally representative of the bulk material as specified in the Purchase Order and the Analytical Procedures; (iii) all samples have been taken from the same batch (i.e. same production run) as the Goods supplied pursuant to a Purchase Order, and (iv) Goods supplied pursuant to the Purchase Order are uniform in composition and homogenous within the tolerances of the Specifications and the Analytical Procedures and any random sample taken from the Goods will conform to the Specifications and the Analytical Procedures.

Analytical Procedures. The Contractor must obtain all testing data related to this work from a reliable laboratory. The Contractor must conduct routine inspections of all off-site laboratories (which are under the Contractor’s employment) in order to assess the internal quality assurance/quality control (QA/QC) programs’ materials, equipment, and processes. All analytical services must be completed according to the Environmental Protection Agency's approved methods and other standards (National Voluntary Laboratory Accreditation Program (NVLAP) and National Institute of Standards and Technology (NIST)) required to ensure continued accreditation of the analytical laboratory. The Contractor must maintain a quality assurance and quality control program (QA/QC) that is approved by the County. The QA/QC program must include field, laboratory, and data components. The field QA/QC program must be designed in a way that prevents any compromise on sample quality or sample analyses during handling and transport. The laboratory QA/QC program must include analysis of blank, duplicate, and spiked samples to verify the precision and accuracy of the analyses. Additionally, compliance with all supplementary QA/QC procedures established by the accredited laboratory is required. Prior to their submission to the County, the results of the sample analyses shall be subject to review as part of the data QA/QC program. The Contractor must advise the appropriate County personnel on whether to accept or reject any suspicious or nonconforming results following a discussion with said personnel.

Analytical Procedures. Analytical procedures are used in the planning and final stages of the audit. In the planning phase, we use analytical procedures to identify unusual financial transactions and compare relationships to expected results. We compare current-year information to the prior years for balance sheet items, revenues, and expenditures. In the final stages of the audit, the financial statements are reviewed to identify expected relationships, such as comparing debt paid to expenditures recorded on governmental funds, transfers between funds, depreciation expense, etc. For all significant relationships identified, explanations are obtained as to why the situation occurred and additional audit procedures are applied to resolve any concerns.
