Dioxin determination in ambient air
The Soxhlet extraction of dioxins from different environmental matrices is described by the regulated methods EPA 1613. This Application note describes the extraction of dioxins from particulate matter air samples collected on quartz fiber filters and on polyurethane foam cartridges using the BUCHI UniversalExtractor E-800. The extracts were analyzed by GC-MS.
