USGS Method O 5505 03 a Lab Technique for Research studies in Geology

• This method is suitable for the determination of polycyclic aromatic hydrocarbons in soil and sediment samples containing at least 10 ug/kg of each PAH compound.

• This method is applicable to compounds that are efficiently extracted from sediment by a dichloromethane/methanol azeotrope, adequately separated from natural coextracted compounds by gel permeation chromatography, and sufficiently volatile and thermally stable for determination by gas chromatography/mass spectrometry.
