Hard cap espresso machine for the quantitative extraction of PCBs in soils. Preconcentration step by stir bar sorptive extraction provides LODs in the ppt range. Extraction efficiency was compared with that of pressurized solvent extraction. Trueness was evaluated by the analysis of a reference certified material.
