Spectroscopy-Based Tool Detects, Measures Contaminants in Landfills

SÃO CARLOS, Brazil, May 16, 2017 — A method known as laser-induced breakdown spectroscopy (LIBS) could offer a cleaner, faster and simpler approach than existing technologies for detecting contaminants in the fluids coming from landfills. Although conventional LIBS presents some limitations when used in the single-pulse configuration, the use of LIBS in the double-pulse (DP) configuration demonstrated rapid detection of mercury (Hg) and could potentially be applied to other contaminants. Targeting a leachate sample with a high-intensity double-pulse laser generates an extremely hot plasma. The light emitted by the plasma is...Read full article
