Identification of high-molecular weight brominated flame retardants in environmental samples using GC/Q-TOF

摘要

Experimental data indicate that there is excellent agreement between the calculated and experimental relative abundances of the isotope clusters of BFRs, thus making possible formula generation from the accurate mass of the molecular ion. Enhanced selectivity of the high efficiency soft ionization source has enabled identification of these high molecular weight BFRs and their detection at picogram levels in spiked environmental samples.
