Gas chromatography (GC) with packed and capillary columns, high-performance liquid chromatography (HPLC) and thin-layer chromatography have been used to characterize various commercially available mixtures of polychlorinated terphenyls (PCTs). Besides, UV absorption and mass spectrometry data have been collected, and the behaviour of PCTs upon perchlorination to the tetradecachloroterphenyls has been studied. Using GC, the PCT content of a number of paper and sewage sludge samples has been determined. The application of perchlorination/GC as method of analysis often yields unreliable, i.e., too high, results compared with the direct GC pattern-comparison method. In the case of paper samples, hydrogenated terphenyls appear to be the principal interfering compounds.
已使用填充柱和毛细管柱气相色谱法（GC）、高效液相色谱法（HPLC）和薄层色谱法对各种市售多氯三联苯（PCT）混合物进行表征。此外，还收集了紫外吸收和质谱数据，并研究了PCT全氯化生成十四氯三联苯后的行为。使用气相色谱法测定了一些纸张和污水污泥样品中的PCT含量。与直接气相色谱图谱比较法相比，采用全氯化/气相色谱法作为分析方法往往会得出不可靠的结果，即结果偏高。对于纸张样品，氢化三联苯似乎是主要的干扰化合物。
