Dioxin & Furan Analysis

Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) can be formed as byproducts of combustion and certain industrial manufacturing processes. They are persistent organic compounds in the environment and can bioaccumulate in the food chain.

There are 7 PCDD isomers and 10 PCDF isomers. The most studied isomer from this family of compounds is 2,3,7,8-tetrachlorodibenzop-dioxin (2,3,7,8-TCDD), which is used as the relative toxicity reference for the other isomers. Given the toxicity concerns, applicable regulatory criteria established for various environmental media are typically in the parts per trillion and
parts per quadrillion ranges.

Analytical Approaches:

Alpha Analytical offers PCDD / PCDF analysis by both EPA methods 8290A and 1613B for the reporting of the 17 dioxin and furan isomers as well as the tetra- thru octachlorinated dioxin and furan homolog series. Applicable sample matrices include aqueous, soil, sediment, and tissues. Please see the PCDD/PCDF target compound list included below for reporting limit information.

Analysis Alpha Analytical utilizes Thermo high resolution mass spectrometer (HRMS) instrumentation equipped with dual Model 1310 gas chromatographs. This dual data acquisition configuration greatly increases analytical efficiencies and productivity. A number of different sample extraction and extract clean up protocols are available, depending on the sample media and project specific requirements.

Reporting Formats:

Several reporting format options are also available including reporting only 2,3,7,8–TCDD. Report formats include total dioxins and furans within a homolog series, as well as total dioxins and furans. Toxic Equivalents (TEQ) are also reported using the Toxic Equivalency Factor (TEF) values specified in a project-specific Quality Assurance Project Plan (QAPP).


Alpha Analytical holds NELAP as well as several other state certification for dioxins and furans. Alpha also holds Department of Defense (DOD) certification and we are fully compliant with DOD/DOE QSM 5.1 Appendix B, 2017.
