| Abstract: | A two dimensional separation system of gas chromatography (SE-54 column)- gas chromatography (FFAP column)with FID/ ECD dual-detector in parallel is presented. Fractions cut from the SE-54 column are separated instantly by the FFAP column without the necessity to use cold trapping technique.The method developed is proved to be useful for fractionating and analyzing complex mixtures as in the case of trace analyses of toxins in PCDDs and PCBs environmental samples. |
