Application guide: LIBS
Laser-Induced Breakdown Spectroscopy (LIBS) is an elemental analysis technique that uses high-energy laser pulses to irradiate a sample and generate high-temperature plasma on the sample surface. By analyzing the characteristic atomic and ionic emission spectra generated during plasma cooling, LIBS enables rapid qualitative and quantitative elemental analysis.
