Polybrominated diphenyl ethers (PBDEs) were developed in the early 1970s and are used as flame retardants for various consumer products, including clothing, furniture, and plastics. Accelerated Solvent Extraction (ASE), introduced in 1995, was EPA approved under method 3545A and has proven to be a valuable technique for environmental laboratories. In this application note, PBDEs were extracted from human breast milk (freeze dried), sediments, fish tissues, and polymers using ASE.

Accelerated Solvent Extraction (ASE) uses solvents at elevated temperatures and pressures to extract organic materials from solid and semisolid samples in a fraction of the time required by traditional extraction procedures. This Application Note details procedures for extracting the following contaminants from animal tissues: Dioxins/Furans, Polybrominated Flame Retardants (PBDE), PCBs, pesticides, PAHs, and organo-tin.

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.

多溴联苯醚类化合物含有电负性基团，用NCI 模式检测灵敏度较高，在实际样品测定时，NCI 由于具有很高的选择性，因此能去除基质干扰，能体现出更大的优势。赛默飞的ISQ 单四级杆气质联用仪具有不泄真空更换离子源的优势，适合该类化合物的检测应用技术的推广。

The Thermo Scientific HPLC system is applied for the determination of polybrominated diphenyl ethers (PBDEs). The separation is performed on a Thermo Scientific Hypersil GOLD Phenyl UHPLC column, with UV detection at 230 nm.
