The operating condition for fractionation of PCDDs/PCDFs congeners in prepared exhaust gas sample extracted solution by modified multi-dimensional gas chromatograph (MMD-GC) system was established and each peaks appeared on the chromatogram obtained by ENV-17 MS capillary column were assigned in this study. Each PCDDs/PCDFs congeners were separated and fractionated by BPX-DXN fused silica capillary column by which PCDDs/PCDFs peaks assignment has been already confirmed. The fractionation of each peaks to deactivated capillary tube were performed by heart-cut technique using liquid carbon dioxide. Trapped congeners were eluted by dichloromethane to appropriate test tubes and Decane was added as a keeper solvent prior to concentration.<BR>This MMD-GC fractionation technique was useful for the peak assignment appeared on capillary gas chromatographic column for environmental contaminants having complicated isomer or congener composition.
