Furthermore, the entire sample is consumed, ruling out another analysis.
In this article, we present a new technique of metal analysis: the TRELIBS (Time Resolved Laser Induced Breakdown Spectroscopy) by a direct analysis of exhaust particulate collected on filter, avoiding the destruction of sample. After a presentation of this new technique and the results obtained on diesel particulate analysis, these results are compared to SEM/EDS (Scanning Electron Microscopy with Energy Dispersing Spectrometry) and ESR (Electron Spin Resonance) results. Also, an organic analysis method on PAH (Polycyclic Aromatic Hydrocarbon) was developed by GC/MS (Gas Chromatography coupled to Mass Spectrometry). Furthermore, the chemical characterization of diesel particulates will be linked to engine parameters (fuel type and air/fuel ratio).
