Sample preparation and chromatographic methods applied to congener-specific analysis of polybrominated diphenyl ethers

Abstract

This chapter reviews the recent literature and highlights the technical and methodological improvements in the analysis of polybrominated diphenyl ethers (PBDEs). Sample preparation, extraction of the analytes and clean-up are discussed with emphasis on recent developments. Gas chromatography coupled with mass spectrometry (GC-MS) is discussed for the instrumental analysis of PBDEs. The most important parameters that may affect accurate measurements of PBDEs are also included. Information related to quality assurance/quality control (QA/QC) procedures used in the analysis of PBDEs, including method validation parameters and possible sources for biased results, is given in detail. An overview of recent inter-laboratory studies on PBDEs and a discussion of the scores and outcomes conclude the chapter.
