Aerosol analysis by micro Laser-Induced Breakdown Spectroscopy: a new protocol for particulate matter characterization in filters

In this research, we investigate the minor chemical elements contained in the diesel particulate matter (DPM) exhaust emissions, generated by in-use diesel engine passenger vehicles. For this purpose, we apply a high-resolution optical emission spectroscopy technique, for precise spectrochemical analysis of diesel particulate matter. By means of laser-induced breakdown spectroscopy (LIBS) analytical method, we qualitatively and quantitatively characterise detected minor chemical elements in DPM. Particulate matter samples were obtained from in-use diesel engine passenger vehicles of diverse types and models from major brand car producers in Europe. We analysed particulate matter, extracted from the exhaust manifold part, from vehicles, which are used in daily life environment. The LIBS technique has revealed the presence of minor chemical elements in DPM -silicon, nickel, titan, potassium, strontium, and molybdenum with diverse concentrations.

Laser Induced Breakdown

This research qualitatively and quantitatively characterises the minor chemical elements in diesel particulate matter (DPM). DPM was extracted from in-use diesel engine passenger vehicles of diverse types and models from major brand car producers in Europe. We analysed particulate matter extracted from the exhaust manifold part from passenger vehicles that are used in daily life environment. To qualitatively and quantitatively characterise the DPM, we employed the high-resolution Laser-Induced Breakdown Spectroscopy analytical technique (LIBS). Qualitative spectrochemical LIBS analyses confirmed the presence of minor chemical elements—silicon, nickel, titan, potassium, strontium, and molybdenum in DPM. For quantification of the LIBS signal, the calibration functions were constructed from internal calibration standards. Different concentrations of detected minor elements Si, Ni, Ti, K, Sr, and Mo were measured with respect to the type of complex particulate matter.
