| Abstract |
Methods for the analysis of polybrominated biphenyls (PBBs) by gas chromatography/mass spectrometry/computer (GC/MS/COMP) were developed using a 45 cm x 0.2 cm i.d. glass column packed with 2% OV-101 coated on Gas-Chrom Q. The column was programmed from 150-300C at 20C/min for the chromatography of mono-through pentabromobiphenyl and from 220-300C at 12C/min for hexa- through decabromobiphenyl. Two separate analyses were required to adequately separate the lower isomers and to yield definitive peaks for the higher isomers. A total of 80 samples were analyzed by GC/MS in the Multiple Ion Detection (MID) mode. They contained from undetectable to 860 micrograms/ml of PBBs. The higher isomers accounted for the majority of the PBBs found. Mass spectra obtained during GC/MS analysis of some of the more highly concentrated samples not only confirmed the presence of PBBs, but also detected polybrominated biphenyl ethers and other brominated compounds. Three commercial samples of decabromobiphenyl ether (C12Br10O) were analyzed for impurities by GC/MS using the same conditions as for the higher PBBs. All three samples contained C12Br9ClO in small amounts and one sample contained traces of C12H2Br8O and C12HBr9O. |
