Polychlorodibenzothiophenes (PCDTs) have been found in several kinds of environmental samples. The lack of reference compounds has meant that very little is known about their gas chromatographic behavior. Here we discuss the retention of 19 authentic PCDTs and their sulfones on the widely used gas chromatographic stationary phases DB-5 and DB-5ms. The retention order is different from that of the polychlorodibenzofurans. The data generated allowed us to carry out a multiple linear regression to generate parameters for predicting the retention indices of unknown congeners based only on their structural features.
多氯二苯并噻吩（PCDTs）已在多种环境样品中被发现。由于缺乏参考化合物，人们对它们的气相色谱行为知之甚少。在此，我们讨论了19种纯正PCDTs及其砜类化合物在广泛使用的气相色谱固定相DB - 5和DB - 5ms上的保留情况。其保留顺序与多氯二苯并呋喃不同。所生成的数据使我们能够进行多元线性回归，以生成仅基于未知同系物的结构特征来预测其保留指数的参数。
