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 13C-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.
描述了一种用于对人和动物源样品中多氯二苯并 - 对 - 二噁英和二苯并呋喃进行异构体特异性定量的分析程序。它包括大规模净化,其中包括各种柱色谱法,以及参考内部13C标记标准的高分辨率气相色谱/质谱定量法。通过额外应用凝胶渗透色谱法和使用保留间隙,实现了低皮克/升范围(10^(-15))的检测限。
