摘要：

A highly automated extraction and clean-up method for polychlorinated dibenzodioxins and polychlorinated dibenzofurans is described. The method includes the use of gel permeation chromatography, alumina clean-up and porous graphitized carbon chromatography, followed by analysis by gas chromatography high-resolution mass spectrometry. The procedure allows for the analysis of six milk samples per day in addition to two quality control samples and a blank. Detection limits on a fat basis for the individual congeners in milk samples are in the sub-ppt range. Long-term performance was investigated and data are given for reproducibility, precision and accuracy.
