“…Song et al 6 have recently published a review specifically about the instrumentation used in LIBS, though several other reviews [1][2][3][4][5][6][7][8][9][10][11] about LIBS applications also discuss the instrumentation related to this technique. In addition, reviews about general spectroscopic instrumentation, detectors for spectrometry, and lasers are Figure 3.…”

“…The collective behavior of the optically dense plasma obtained at high power density defines a plasma resonant frequency, υ p, given by υ p = (4πn e e 2 / m e ) ½ = 8.9 x 10 3 (n e ) ½ (2) in which n e is the electron density (cm -3 ), in the plasma, e, is the electron charge, and m e , is the electron mass. There could be a critical electron density for what the plasma frequency equals the laser frequency, υ l , (υ p = υ l ).…”

“…The technique is named Laser Induced Breakdown Spectroscopy (LIBS) and numerous reviews [1][2][3][4][5][6][7][8][9][10][11] and three recent text books [12][13][14] have already been published addressing both general and specific aspects, in the relatively short period after the technique had undergone a renewed interest in the beginnings of the eighties. On the other hand, the technique has recently experienced an exponential growth in interest, reflected by an increasing number of publications, and, apparently, its niche in the general field of Analytical Chemistry are ready to be defined.…”

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, LIBS) e sua principal característica está no uso de pulsos de laser como fonte de energia para vaporizar a amostra e excitar a emissão de radiação eletromagnética, a partir de seus elementos e/ou fragmentos moleculares. A radiação emitida é analisada por meio de instrumentos ópticos de alta resolução e as suas intensidades são medidas, usualmente com detectores rápidos de estado sólido. Em conjunto, esses dispositivos permitem a geração e a medida de um espectro de emissão de faixa ampla do fenômeno induzido pelo pulso de laser. O espectro registrado contém informação qualitativa e quantitativa que pode ser correlacionada com a identidade da amostra ou empregada na determinação da quantidade de seus constituintes. Essa revisão é dividida em quatro partes. A primeira aborda aspectos históricos da técnica e os conceitos teóricos relevantes associados com LIBS; então, os aspectos práticos de diversas abordagens experimentais e instrumentais empregadas na implementação da técnica são revistos de forma crítica; as aplicações encontradas na literatura, incluindo aquelas que empregam quimiometria, são classificadas e exemplificadas por meio de trabalhos relevantes recentemente publicados. Finalmente, uma tentativa de estabelecer uma avaliação global e as perspectivas futuras para a técnica é apresentada.This review describes the fundamentals, instrumentation, applications and future trends of an analytical technique that is in its early stages of consolidation and is establishing its definitive niches among modern spectrometric techniques. The technique has been named Laser Induced Breakdown Spectroscopy (LIBS) and its main characteristic stands in the use of short laser pulses as the energy source to vaporize samples and excite the emission of electromagnetic radiation from its elements and/or molecular fragments. The emitted radiation is analyzed by high resolution optics and the intensities are recorded, usually by fast triggered solid state detectors. Together, these devices allow producing and registering a wide ranging emission spectrum of the short-lived phenomenon induced by the laser pulse. The spectrum contains qualitative and quantitative information which can be correlated with sample identity or can be used to determine the amount of its constituents. This review is divided in four parts. First, the relevant historical and theoretical concepts associated with LIBS are presented; then the main practical aspects of the several experimental and instrumental approaches employed for implementation of the technique are critically described; the applications related in the literature, including those making use of chemometri...

“…Samples are usually housed in a pressurevariable chamber mounted with an adjustable sample stage. One widely used detection technique is laser-induced breakdown spectroscopy (LIBS), in which an optical spectrometer is used to collect light emission from the laser-produced mass plasma at the sample surface (10)(11)(12)(13). Typical LIBS spectra include atomic and ionic emission lines superimposed on a broadband continuum resulting primarily from electron-ion recombination.…”

“…[1][2][3][4][5][6][7][8][9][10][11] In the LIBS technique, a high-power laser beam is used to vaporize and excite the sample in situ in a single step. This is accomplished by focusing a pulsed laser beam at the test point to produce a laser-induced plasma.…”

Laser-induced breakdown spectroscopy (LIBS) has been evaluated as a multimetal continuous emissions monitor (CEM) at the U.S. Environmental Protection Agency (EPA) rotary kiln incinerator simulator (RKIS) facility in Raleigh, NC. Two detection systems with a bifurcated optical fiber bundle were used for simultaneously monitoring the concentrations of Be, Cd, Cr, and Hg in the test. Two calibration techniques were evaluated in the laboratory for the field measurements. On-line calibration of relative metal concentration was also performed in the simulated incinerator gas stream. Toxic metal concentrations measured with LIBS have been compared with the EPA reference method (RM) results.
