Key Considerations when utilizing laser-induced breakdown spectroscopy

Hosted by Photonics Spectra:
Laser-induced breakdown spectroscopy (LIBS) is a fast, nondestructive analytical technique that uses a laser to generate a plasma on the surface of a sample, producing emission spectra that can be analyzed to determine the elemental composition of the material. Gilmore introduces the fundamental principles of LIBS and its applications in various fields, including environmental monitoring, material science, and forensic analysis.
Gilmore covers the basic components of a LIBS system, including the laser source, sample holder, and spectrometer. He also discusses the different types of lasers and spectrometers used in LIBS, including specific emphasis on the electronic shuttering necessary to record a LIBS spectrum. LIBS has multiple applications in environmental monitoring, including the analysis of soil and water samples for pollutants such as heavy metals. Gilmore also speaks on the use of LIBS in metal recycling for material identification and quality control as well as its potential use in inline inspection systems.
Finally, he highlights ongoing efforts aimed at improving LIBS, including the development of resistive-gate CCDs, high-power laser systems, and data analysis algorithms. Overall, this presentation provides a comprehensive overview of a LIBS system, addressing the key performance parameters of each component.
