·
We routinely use high performance liquid chromatography
(HPLC) for PAH analysis because it offers better sensitivity than GC-MS, and it
permits compound confirmation by use of fluorescence – UV dual detectors,
·
GC/MS analysis in the SIM mode for PNAs is our norm by
mass spectrometry because of its greatly increased sensitivity relative to the
normal GC-MS scan mode.

PNA and PAH are the same thing. PNA= PolyNuclear Aromatic
Hydrocarbon
