An analytical procedure for the isomer‐specific quantification of polychlorinated dibenzo‐ p ‐dioxins and dibenzofurans in samples of human and animal origin is described. It consists of a large‐scale clean‐up including various kinds of column chromatography and high‐resolution gas chromatographic/mass spectrometric quantification referring to internal 13 C‐labelled standards. By additional application of gel‐permeation chromatography and the use of a retention gap, detection limits in the low ppq range (10 −15 ) were achieved.
