The development of an analytical method for the analysis of PCDD/PCDF in fly ash using a bench analytical system comprising of a gas chromatograph fitted with an ion trap detector operated in the tandem MS mode is described. The optimum settings for the most important MS/MS parameters are given, including those for the less reported mono- to tri-chlorinated dioxin and furan congener groups. Fly ash samples from three waste incineration plants representing a de-commissioned 1970s plant design, an upgraded and still operating plant originally designed in the 1970s, and a modern 1990s design operating plant have been analysed for PCDD/PCDF. The fly ash samples were analysed for PCDD/PCDF using the methods developed and the total PCDD/PCDF, I-TEQ values and isomeric profiles are reported. The fly ash from the older de-commissioned incinerator had very significantly higher concentrations of PCDD/PCDF compared to the modern incinerator fly ash.
描述了一种使用台式分析系统分析飞灰中多氯二苯并二恶英/多氯二苯并呋喃（PCDD/PCDF）的分析方法，该系统由配备离子阱检测器并以串联质谱模式运行的气相色谱仪组成。给出了最重要的质谱/质谱参数的最佳设置，包括较少报道的一至三氯二恶英和呋喃同系物组的参数。对来自三个垃圾焚烧厂的飞灰样品进行了PCDD/PCDF分析，这三个厂分别代表了一个20世纪70年代退役的工厂设计、一个升级后仍在运行的20世纪70年代原始设计的工厂以及一个20世纪90年代设计的现代化运行工厂。使用所开发的方法对飞灰样品进行PCDD/PCDF分析，并报告了总PCDD/PCDF、国际毒性当量（I-TEQ）值和异构体分布。与现代化焚烧炉飞灰相比，较旧的退役焚烧炉的飞灰中PCDD/PCDF浓度显著更高。
