Determination of PCBs, PCDDs and PCDFs in insulating oil samples from stored Chinese electrical capacitors by HRGC/HRMS

► Chinese PCBs oil (PCB3) was firstly determined by isotope dilution using HRGC/HRMS. ► Homologue and congener profiles of PCBs was firstly reported. ► TriCBs, TetraCBs, and DiCBs were found to be most abundant. ► Twelve PCB congeners account for more than 50% of the total PCBs concentration. ► Deta...
