Laser-Induced Breakdown Spectroscopy (LIBS)
LIBS is one of the elemental analysis techniques relying on optical emission spectroscopy. In LIBS, a pulsed laser beam is focused on the sample surface to ablate the material and ignite plasma. The laser-generated plasma expands rapidly dissipating energies in forms of sounds, optical emissions, etc. Recording the optical emission spectra, elemental composition of the sample can be revealed. LIBS is employed for both quantitative analysis and material classification/screening. Also, in comparison with other conventional elemental analysis techniques, LIBS can be instrumented into various platforms including handheld device, telescopic optics for remote detection, customized instruments beside manufacturing lines, etc. Collaboration between the LIBS developer and engineers in other fields creates a synergy effect in application of LIBS.
