Jun 23, 2014 · LIBS uses a highly energetic laser pulse to induce breakdown of a sample's surface, atomizing and exciting it. The spectrometer then analyzes the light emitted from the laser-induced plasma. LIBS allows for rapid, multi-elemental analysis of solids, liquids, and gases with little to no sample preparation.

Apr 5, 2019 · LIBS is an analytical method by which one can determine (qualitatively and quantitatively) the elemental composition of solid, liquid or gas samples. LIBS focused laser pulses vaporize, atomize and excite the sample plasma emission.

with unique LIBS spectral peaks. By identifying different peaks for the analyzed samples, its chemical composition can be rapidly determined. Often, information on LIBS peak intensities can be used to quantify the concentration of trace and major elements in the sample. With the advancement of powerful chemometric software for LIBS data ...
