Noureddine Melikechi of the Department of Physics and Applied Physics at the University of Massachusetts (Lowell, MA) saw an urgent need for the development of an untargeted and unbiased method to distinguish Gulf War illness (GWI) patients from non-GWI patients; he and his associates utilized laser-induced breakdown spectroscopy (LIBS) in their efforts to meet that need.

Diagnosis of Gulf War Illness Using Laser-Induced Spectra Acquired from Blood Samples

Mohamed Abdel-Harith of Cairo University and his team explored using BRELIBS for the elemental analysis of the synagogue’s glass shards. Their findings reveal the potential of BRELIBS in conducting elemental analysis on transparent materials. Spectroscopy recently spoke to Abdel-Harith about this work.

Using Back-Reflection-Enhanced Laser-Induced Breakdown Spectroscopy (BRELIBS) for the Elemental Analysis of Transparent Materials

Meat fraud has emerged as a growing concern globally. The adulteration, substitution, or mislabeling of meat products has resulted in negative economic effects, such as unfair competition in the global marketplace, as well as ethical concerns, because consumers want to know what is in the meat they are consuming. Ismail H. Boyaci of Hacettepe University and his team have explored using laser-induced breakdown spectroscopy (LIBS) for protein-based analysis and the identification of meat species. Spectroscopy recently spoke to Boyaci about this work. 

Using Laser-Induced Breakdown Spectroscopy (LIBS) for Protein-Based Analysis and the Identification of Meat Species

The fast data acquisition and minimal sample preparation of handheld LIBS devices make them very useful for geochemical mapping, resource prospecting, sample selection, and hazard identification.

Handheld Laser-Induced Breakdown Spectroscopy (hLIBS): A Valuable Tool for Terrestrial and Extraterrestrial Recognition of Meteorites in the Field

Emmanuel Lalla of York University in Toronto, Ontario, Canada, as well as his co-authors, recently presented an in-depth characterization of a set of samples collected during a 28-day Mars analog mission conducted by the Austrian Space Forum in the Dhofar region of Oman. Lalla spoke to Spectroscopy about this research, as well as how various methods of spectroscopic analysis can complement each other in analysis.

Combined Spectroscopic Analysis of Terrestrial Analogs from a Simulated Astronaut Mission Using the Laser-Induced Breakdown Spectroscopy (LIBS) Raman Sensor

Laser-induced breakdown spectroscopy (LIBS) is an ideal method for elemental analysis of geological samples, and has been used by NASA on the Mars rovers. This article details the methodology and the most successful calibration and quantification methods to date.

Geochemical Analysis Using Laser-Induced Breakdown Spectroscopy

We investigate the effect of an applied electric field on the laser-induced titanium plasma for laser induced breakdown spectroscopy (LIBS) for the purpose of assessing electron density with respect to laser energy.
