| Abstract: | This study was directed to the sample preparation techniques for the determination of PCBs in transformer oils. The optimum conditions of PCBs seperation/determination were established. The purified extract was examined for PCBs by gas chromatography with electron-capture detector. Recoveries were in the range of 86-110% and the coefficient of variation was 1-3%. In addition, a qualitative analysis for PCBs in transformer oils was carried out by gas chromatography and mass spectroscopy. |
