Sample Temperature Effect on Steel Measurement Using SP-LIBS and Collinear Long-short DP-LIBS

Moisture Measurement Using LIBS

LIBS is traditionally an atomic emission spectroscopy involving sampling, atomization and excitation of a sample by laser ablation. The radiative cooling of the created plasma is spectrally analyzed to provide the elemental composition of a sample of interest. In 1962, two years after the invention of the laser, Jarrell Ash Co. developed the Laser Microprobe that revolutionized the elemental mi...

Effect of Atmospheric Conditions on LIBS Spectra

Laser-induced breakdown spectroscopy (LIBS) is typically performed at ambient Earth atmospheric conditions. However, interest in LIBS in other atmospheric conditions has increased in recent years, especially for use in space exploration (e.g., Mars and Lunar) or to improve resolution for isotopic signatures. This review focuses on what has been reported about the performance of LIBS in reduced ...

Elemental Abundance Measurement Using Micro-libs for Space Exploration

Introduction: As LIBS has been applied to a wider and more useful range of samples, it has been realized that signals generated with the laser plasma are highly dependent upon the matrix from which they have been ablated. In this case, analytical results dependence on physical properties of the sample. This at times leads to the paradoxical situation where precisely matrix matched calibration s...

Laser Induced Breakdown Spectroscopy (LIBS)

Absolute LIBS stratigraphy with Optical Coherence Tomography

In this contribution preliminary studies on the application of Optical Coherence Tomography (OCT) to absolute depth calibration of Laser Induced Breakdown Spectroscopy (LIBS) data in application to revealing stratigraphy of easel paintings are presented. The procedure of in-situ monitoring of LIBS by means of OCT is described. Numerical method developed for precise extraction of the depth of th...
