Gas Chromatography High Resolution Time-of-Flight Mass Spectrometry (GCHRT)

In this application note Gas Chromatography High Resolution Time-of-Flight Mass Spectrometry (GCHRT) was used for the analysis of PBDEs in sediment and fish biota samples. The 13 samples were fortified with labelled PBDE standards and dissolved in 12 nonane for analysis. Chromatographic separations were performed using an Agilent 7890 GC and 7693 auto sampler. Mass spectral data were collected using the Pegasus GC-HRT, yielding a mass resolving power of 25,000 (FWHM).
