摘要
本文介绍了以选择离子检测方式的气相色谱-离子阱检测器(SIM/GC/ITD)分析土样中ppt级多氯二苯并-对-二噁英的方法。该法所用仪器简单,操作简便,净化效率和回收率高。当组分浓度在ppt～ppb范围、母体组成在很大范围变动时,也有较好的重复性。
A SIM/GC/ITD method is described for the analysis of polychlorodibenzo-p-dioxins at
Parts per trillion level in soil. The method has a high recovery and reproducibility with the
component concentration ranging from ppt to ppb (parts per billion), and the matrix varying
widely.
