| Abstract: | Combining capillary GC with ion-trap detection in the MS/MS mode allows the determination of trace levels of the highly toxic PCB congeners, CB 77, 126 and 169 in complex biological tissues, suspended matter and sediment. The high selectivity and sensitivity of MS/MS detection in the resonant and non-resonant modes yield detection limits of 60 fg, 300 fg and 200 fg for CB 77, 126, and 169, respectively. |
