Accurate quantification of polycyclic aromatic hydrocarbons in dust samples using microwave-assisted solvent extraction combined with isotope-dilution mass spectrometry

► We applied MAE-IDMS for accurate quantification of PAHs in dust samples. ► Both partitioning and isotopic equilibria can be achieved using this technique. ► MAE-IDMS can provide accurate concentrations even if extraction efficiencies were low. ► Characteristics of samples strongly affected for low extraction efficiencies of PAHs.
