New research discusses the development of laser-induced XUV spectroscopy (LIXS) as an improvement to laser-induced breakdown spectroscopy (LIBS) for rapid in situ microanalysis of materials, with the ability to determine light elements and halogens with high precision and detection limits.
A study shows that microwave-enhanced laser-induced breakdown spectroscopy (MWE-LIBS) can effectively analyze zirconium metals and oxides in nuclear fuel debris. The study found that microwaves lower the excitation temperature and increase ionization of zirconium, resulting in consistent enhancements in zirconium emissions with a higher signal-to-noise (S/N) ratio across all sample types.
