1 Daniel Skinner Qualitative Analysis by Laser-Induced Breakdown in Aqueous Media Daniel Skinner[1] 1 Department of Physics, The University of York, York, YO10 5DD, UK Abstract A pulsed, focused laser beam is used to induce dielectric breakdown (LIB) in various solid metallic targets and bulk aqueous samples. Emission from the breakdown plasma is investigated using a non time resolved technique with the feasibility of qualitative elemental analysis in mind.
