A first sampling campaign performed on the PowerJet SaM-146 turbofan (SNECMA/Saturn) provided soot particles collected on quartz fiber filters in four engine regimes (30 %, 70 %, 85 % and 100 %). Two-Step (Desorption/Ionization) Laser Mass Spectrometry (L2MS) and Time of Fight Secondary Ion Mass Spectrometry (ToF-SIMS) techniques were used to analyze the surface chemical composition of the soot particles, with special focus on PAHs. In L2MS, the adsorbed phase is probed by nanosecond laser desorption (532nm), then the ejected molecules are ionized with a second ns laser (266nm) and further mass-separated by ToF-MS.Show less >
