Rapid Detection of Oil Pollution in Soil by Using Laser-Induced Breakdown Spectroscopy

Detection of uranium using laser-induced breakdown spectroscopy.

The goal of this work is a detailed study of uranium detection by laser-induced breakdown spectroscopy (LIBS) for application to activities associated with environmental surveillance and detecting weapons of mass destruction (WMD). The study was used to assist development of LIBS instruments for standoff detection of bulk radiological and nuclear materials and these materials distributed as con...

Rapid Detection of Heavy Metal Contents in Fruits by Laser Induced Breakdown Spectroscopy

To detect heavy metal contents in fruits rapidly, the Citrus Nanfeng tangerines pericarp and flesh have been analyzed by laser induced breakdown spectroscopy. Line emissions from five heavy metal elements, Pb, Cd, Hg,Cr and As, have been clearly extracted. Their intensities correspond to relative concentrations of these elements contained in the analyzed samples. The results demonstrated that t...

Laser Induced Breakdown Spectroscopy

Laser-induced breakdown spectroscopy (LIBS) is a powerful analytical technique that can be used for the detection and characterization of materials. In LIBS, a focused laser beam is used to generate a plasma plume on the surface of solid and liquid samples or inside the sample volume of gases, liquids, and aerosols. Each excited atom in the plasma emits a unique set of spectral lines, particula...

Laser Induced Breakdown Spectroscopy

Esta revisão descreve os aspectos fundamentais, a instrumentação, as aplicações e tendências futuras de uma técnica analítica que se encontra em seu estágio de consolidação e que está em vias de estabelecer o seu nicho entre as técnicas espectrofotométricas modernas. A técnica é denominada Espectroscopia de Emissão em Plasma Induzido por Laser (em inglês, Laser Induced Breakdown Spectroscopy, L...
