Laser-Induced Breakdown Spectroscopy

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...

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 gas-breakdown model

2014 A one-dimensional model oriented toward a thorough understanding of line and continuum emission from a CO2 laser-induced helium plasma is presented. The model combines a time-dependent calculation of the ionization and radiation dynamics with a lagrangian hydrodynamic simulation code. Detailed collisional radiative models involving many neutral and ion excited levels are used to predict th...
