In the optimised instrumental conditions, abundance and repeatability improved with increase in temperature of the ion source. The instrumental detection limits (IDLs) for BDE-196, BDE-197, BDE-206, BDE-207 and BDE-209 were 0.1, 0.1, 0.2, 0.3 and 0.6 pg, respectively. When compared to the previous reports, the IDLs were the same as for electron capture negative ionisation (ECNI) or EI-double focusing magnetic sector (EI-Sector) mass spectrometer, indicating that sensitive determination could be achieved using a conventional GC-EI-qMS. Validation of the method was carried out by the analysis of reference materials and mussel samples. We confirmed that the concentrations quantified using this method was in the range of reported values for reference materials. Similar concentrations were found in mussels, which were analysed previously by our group. Thus, we conclude that a conventional GC-EI-qMS can be applied for analysis of higher brominated PBDEs in various environmental and biota matrices.","2011",,,"International Journal of Environmental Analytical Chemistry","91","4","Taylor & Francis",,"348-356",,,,,,"http://dx.doi.org/10.1080/03067319.2010.496040",,,,,"TRUE",,"0306-7319",,,,,,"","http://www.tandfonline.com/toc/geac20/current","http://scholar.google.co.in/scholar?as_q=%22Optimisation+of+the+analytical+method+for+octa-%2C+nona-+and+deca-brominated+diphenyl+ethers+using+gas+chromatography%E2%80%93quadrupole+mass+spectrometry+and+isotope+dilution%22&num=10&btnG=Search+Scholar&as_ep","author",,"Global COE Program","",,,,,,"",,,,,,,"",,,,,"",,,,,"","",,,,,"","",,,,,
