Implemetation of GCxGC-TOF MS for the Simultaneous Determination of PCBs, PBDEs and PAHs in Environmental Samples.

Popis výsledku v původním jazyce

In this study, comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GCxGC-TOFMS) for the simultaneous determination of 18 polychlorinated biphenyls (PCBs), 7 polybrominated diphenyl ethers (PBDEs) and 16 polycyclic aromatic hydrocarbons (PAHs) was optimized to obtain the best chromatographic resolution and quantification limits (LOQs) of target analytes. Two injection techniques, pulsed splitless and large volume programmable temperature vaporization (LV-PTV), and several capillary column systems were tested within the experiments (BPX-5 and BPX-50 in the 1st dimension and BPX-50, Rt-LC35 and HT-8 in 2nd dimension). All tested combinations of columns were able to separate all target PCBs and PBDEs. Selection ofthe column system was therefore mainly influenced by its ability to separate the critical groups of PAHs (1st group: B[a]A, CP[cd]P and Chr, 2nd group B[f]F, B[k]F and B[b]F, 3rd group DB[ah]A, I[1,2,3-cd]P and B[ghi]P). Although none of
