Abstract

<b>The detection of carbon is conducted by laser-induced breakdown spectroscopy (LIBS) in a flow system designed to replicate aircraft exhaust flow conditions. To generate carbon particles, a glucose solution was evaporated using a ceramic nebulizer and an electrical heater. For elemental analysis, both the C (247.86 nm) and CN band (388.3 nm) peaks were selected for detecting carbon. The signals detected from the emissions stream at velocities of up to 70 m/s showed that in situ characterization of carbon particulates in the high-speed exhaust is feasible.</b>
