Abstract	The main methods of identification and quantification of metallic species in diesel soot require to render metallic species soluble by destruction of solid sample with all the difficulties associated to this analysis such as rate of solubility, destruction of sample, risk of sample pollution during preparation step. Furthermore, a few milligrams of sample are used, then lost and another analysis is not permitted. This article describes a new direct analysis of metals presents in exhaust particles and collected on a filter by using the TRELIBS (Time Resolved Laser Induced Breakdown Spectroscopy), which avoids the complete destruction of the sample. In a few a milliseconds, it is possible to obtain a qualitative and semi-quantitative composition of a complex matrix as diesel particulates: Fe, Mg, Ca, Cu, and Zn appear as the major metallic species. TRELIBS results are compared to SEM/EDS. After a presentation of the properties required by the filter for TRELIBS analysis, the identification of the metallic species collected in the exhaust gas of a diesel engine is presented and compared with another technique (SEM/EDS). The evolutions of the metallic concentrations in diesel particles for different air/fuel ratio are also presented.
