Abstract
Formation and evolution of PAHs in flames are studied using a sampling and collection method, that is a small diameter probe with a gas chromatographic stainless steel column connected immediately downstream of the probe. After the sampling and collection, the column, disconnected from the probe, is inserted into a flame ionization gas chromatograph for the analysis.
Results show that the method provides a complete trapping of PAH, a direct and quantitative analysis of single PAH without manipulation and rapidly, and a sample enrichment when PAHs are present at a very low concentration.
