The determination of dioxins and PCBs in foodstuffs is performed to monitor the potential exposure to humans. A reliable and fast  method is introduced. Proficiency test samples were extracted with the SpeedExtractor E-914, followed by an automated clean-up using a MIURA system and analyzed by GC-HRMS. The determined levels of dioxins, furans, dioxin-like and non-dioxin-like PCBs correspond to the assigned values.
