- Laser-Induced Breakdown Spectroscopy

Research Journal of Pharmacy and Technology, 2016
Laser Induced Breakdown Spectroscopy (LIBS) is an atomic emission spectroscopy technique for a rapid chemical analysis of different type of analytes like solids, liquids and gases. LIBS can often be referred to as its alternative name: laser-induced plasma spectroscopy (LIPS).

Laser-Induced Breakdown Spectroscopy

2015
Abstract Laser-induced breakdown spectroscopy (LIBS) represents a useful analytical tool for elemental analysis of solid or liquid materials. An intense pulsed laser can be employed, focused on the surface of the material, to ignite a spark and generate a plume of gaseous atoms and molecules in a distribution of excited states.

Laser induced breakdown spectroscopy on meteorites

Spectrochimica Acta Part B: Atomic Spectroscopy, 2007
The classification of meteorites when geological analysis is unfeasible is generally made by the spectral line emission ratio of some characteristic elements. Indeed when a meteorite impacts Earth's atmosphere, hot plasma is generated, as a consequence of the braking effect of air, with the consequent ablation of the falling body.

Polarization-resolved laser-induced breakdown spectroscopy

Optics Letters, 2009
It is shown that plasma polarization measurements can be used to enhance the sensitivity of laser-induced breakdown spectroscopy (LIBS). The polarization of the plasma emission is used to suppress the continuum with only slight attenuation of the discrete atomic and ionic spectra.

Absorption laser-induced breakdown spectroscopy

SPIE Proceedings, 2009
Self-absorption is used in laser induced breakdown spectroscopy to obtain quantitative analytical information. In this approach two plasmas are generated with a laser pulse that is split into two beams separated by a few millimeters and incident on the target material.

Nanosecond polarization-resolved laser-induced breakdown spectroscopy

Optics Letters, 2010
It is shown that the continuum emission produced in the ablation of an Al target with nanosecond laser pulses is much more strongly polarized than the discrete line emission. This effect may be utilized to improve the resolution of the laser-induced breakdown spectroscopy spectrum by using a polarizer to filter out the continuum background. The effects

Laser Induced Breakdown Spectroscopy (LIBS)

2010
Abstract : LIBS (Laser Induced Breakdown Spectroscopy) and Raman Spectroscopy address all five threats (CBRNE) for security and force protection applications. Military and civilian First Responders could utilize LIBS for CB, explosive hazards, suspicious powder, and hazardous spill analysis.
