Thermo Fisher Scientific has developed a method for the fast determination of PCDD/Fs in sediments, soils, bottom and fly ash (as incineration by-products) using gas chromatography-tandem mass spectrometry (GC-MS/MS).

Application Note 10336, Determination of PCDD/Fs in Environmental Samples using Accelerated Solvent Extraction and GC-MS/MS, describes a sensitive and accurate GC-MS/MS method for determining levels of dioxins and furans in various environmental samples using GC-MS/MS. Instrumental LOQs using GC-MS/MS were calculated in the low fg/μL concentration ranges. The analysis uses Thermo Scientific™ Dionex™ ASE™ Accelerated Solvent Extractor for rapid sample preparation, along with a Thermo Scientific™ TSQ Quantum XLS Ultra GC-MS/MS with Thermo Scientific TargetQuan 3 Software.
