Functional principle of laser-induced breakdown spectroscopy (LIBS)
Laser-Induced Breakdown Spectroscopy (LIBS) is an optical analysis technique used to determine the elemental composition of materials. A short, high-energy laser pulse is focused onto the surface of the sample. The intense energy creates a hot plasma, which emits light in the UV, visible, and near-infrared range.
This emitted light contains characteristic spectral lines corresponding to the elements present in the material. Using a suitable optical setup and a fiber optic cable, the light is directed into a spectrometer, where it is spectrally analyzed. This enables real-time, qualitative and quantitative analysis of the sample — with no complex sample preparation required.
