Method of Laser-induced Breakdown Detection and Application Examples



The Laser-induced Breakdown Detection is a rather novel and highly sensitive method for the non-invasive determination of both the concentration and the number-weighted mean diameter of nanoparticles (colloids) in liquids. Compared to other methods the limit of detection is lower by several orders of magnitude. Their high surface to masse ratio results in a large sorption capacity that on the one hand offers great technical possibilities, on the other hand colloidal transport of pollutants can be a serious environmental problem.
