AN352: Rapid Determination of Persistent Organic Pollutants (POPs) Using Accelerated Solvent Extraction (ASE)

Instrument Type: Automated Sample Prep

The following compounds are listed by UNEP to be POPS: • Pesticides: Aldrin, Chlordane, DDT, Dieldrin, Endrin, Heptachlor, Mirex, and Toxaphene • Industrial chemicals: Hexachlorobenzene, and PCB (polychlorinated biphenyl) • Chemical by-products (Dioxins): Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD and PCDF) This application note describes methods and results for extraction of the POPs listed above, with tables comparing ASE to traditional extraction methods.

AN342: Determination of PCBs in Large-Volume Fish Tissue Samples Using Accelerated Solvent Extraction (ASE)

Instrument Type: Automated Sample Prep

PCBs are a persistent organic pollutant (POP) and therefore are monitored in marine life including fish. Automated Solvent Extraction (ASE 350) technology, an automated extraction method, has been shown to produce good recoveries of naturally occurring PCBs from fish tissue samples, and is approved for use in U.S. EPA SW-846 Method 3545 for the extraction of PCBs, OCPs, BNAs, OPPs, herbicides, and dioxins and furans. ASE operates at elevated temperatures, thus increasing the efficiency of the extraction process. Here we demonstrate the extraction of PCBs in a raw fish tissue sample.

CAN122: Determination of Persistent Organic Pollutants in Fish Tissues by Accelerated Solvent Extraction and GC-MS/MS

Instrument Type: GCMSMS

Polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs) and polybrominated diphenyl ethers (PBDEs) belong to a broad family of synthetic organic compounds known as halogenated hydrocarbons. Polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs) and polybrominated diphenyl ethers (PBDEs) belong to a broad family of synthetic organic compounds known as halogenated hydrocarbons. The method reported here is applicable for the determination of 29 halogenated hydrocarbons (6 PCBs, 16 OCPs, and 7 PBDEs) in fish tissues.
