ASTM D 8543 : 2023

1.1This test method covers the identification and simultaneous measurement of extractable chlorinated pesticides and polychlorinated biphenyls (PCBs) by gas chromatography/mass spectrometry/mass spectrometry (GC/MS/MS).

1.2This test method has been validated for wastewater influents, effluents, industrial discharges, surface water, and ground water.

1.3This test method is not limited to these particular aqueous matrices; however, the applicability of this test method to other aqueous matrices shall be demonstrated.

1.4This test method is restricted to use by or under the supervision of analysts experienced in the use of a gas chromatograph with tandem mass spectrometry. Each laboratory that uses this test method shall demonstrate the ability to generate results that meet or exceed the performance criteria of this test method.

1.5If sensitivity permits, compound tentative identification of unknowns may be made by analyzing the extract in full-scan mode or, if the system allows simultaneous timed single-reaction monitoring (SRM)/full-scan acquisition. Identify unknown peaks according to Guide D4128.

1.6This test method is performance-based. Minor modifications, as allowed by CFR 40 Part 136.6, may be made to improve the method performance, but changes may not be made to the extraction, the extraction solvent, sample-to-solvent ratio, or the MS/MS detection technique.

1.7Units—The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.

1.8This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.9This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
