WebLIBS is an acronym for Laser Induced Breakdown Spectroscopy. It is an analytical technique used to determine the elemental composition of materials. Handheld LIBS analyzers work by using a high-focused laser to ablate the surface of a sample. A plasma is formed consisting of electronically excited atoms and ions.
