Initial Quantitative Measurements with Handheld LIBS
Don Sackett, Suzanne Moller, Morgan Jennings, and Justin Spott, SciAps
The analytical technique laser induced breakdown spectroscopy (LIBS) for elemental analysis is rapidly evolving from a laboratory-based to a field-able technology. Keys to this evolution include the development of more powerful yet compact, battery operable lasers, and combining the advancing laser technology with powerful processors and compact, high resolution spectrometers. The result is the first generation of truly handheld LIBS-based analyzers, such as the SciAps Z-500 LIBZ analyzer that has been utilized in a number of studies of different material types including alloys, ceramics, catalysts, soils, and glass sample types. This note presents the early quantitative results from several field tests.
