EPA Method 1654A:
PAH Content of Oil by HPLC/UV

An oil sample is diluted in acetonitrile and a 20-?L aliquot is injected into the HPLC. The PAHs are partially separated by HPLC and detected with the UV detector.

This method is designed to determine the polynuclear aromatic hydrocarbon (PAH) content of oil by high-performance liquid chromatography (HPLC) with an ultra-violet absorption (UV) detector. The PAH content is measured and reported as phenanthrene.
