AN351: Rapid Determination of Polybrominated Diphenyl Ethers (PBDEs) in Biosolids and Waste Samples Using Accelerated Solvent Extraction

Instrument Type: Automated Sample Prep

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.

Detection and Quantitation of Brominated and Chlorinated Hydrocarbons by DART with Linear Ion Trap and Triple Quadrupole Technology

Instrument Type: MSMS

Brominated hydrocarbons (BFRs) have been used in various industries for decades. Most chlorinated pesticides (OCs) have been banned in the United States, but their use still occurs in developing countries. The persistence of BFRs and OCs in the environment, potential deleterious activity, makes the detection and monitoring of these compounds an important topic. We propose DART as a simple, rapid, easy-to-use technique; eliminating the need for chromatographic method development, and reducing or eliminating sample preparation, for detection and quantitation of both BFRs and OCs.
