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...

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...

Elementar LIBS Analysis of Biological Samples

Trace element analysis of biological samples can be useful for diagnostics of diseases caused by accumulation of some elements in the organism. The aim of this work was to evaluate the performance of Laser induced breakdown spectroscopy (LIBS) for the determination of elements present in human tissues. We have investigated samples of human liver and human spleen using pulsed Nd:YAG laser operat...

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 ...
