I want to determination 16 PAHs in edible oil by GC-MS. But for this reason that matrix is so difficult, I can't have a good recovery and sensitivity. Please introduce methods for extraction ad analysis of 16 PAHs in edible oil
try this approach: take specific grams of oil and do saponification, which make linear fatty acids water-soluble, while aromatic poly cyclic hydrocarbons remains intact. then, with a simple two-phase extraction and following evaporation of solvent, you will have PAH!
