“…If the target material is a gas, seed electrons will be generated by multiphoton absorption or cascade ionization. The tunnel effect can contribute when irradiances above 10 12 W cm -2 are employed. Cascade ionization will start if, at least, one free electron is present in the path of the laser beam.…”

“…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 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...

“…[1][2][3][4][5][6][7][8][9][10] As no material pre-treatment is needed and due to the swiftness of analysis, this technique offers an attractive solution for a wide range of applications. [8][9][10][11] The analytical performance of LIBS depends strongly on the choice of experimental conditions that influence the laser-produced plasma characteristics.…”

In the present study, a historical set of Late Roman glasses coming from a recently unearthed graveyard located in the small city of Cubas de la Sagra, within the Madrid region (Spain) was compositionally analysed using different techniques such as ultraviolet-visible (UV-Vis) and laser induced fluorescence (LIF) spectroscopies, X-ray fluorescence (XRF) and laser induced breakdown spectroscopy (LIBS). LIBS results, recorded upon nanosecond (ns) and femtosecond (fs) laser irradiation, served for identification of major glass components (to classify them into main historical glass groups) and of minor components (e.g. chromophores, decolouring agents and degradation products). Quantitative information regarding these components was obtained on the basis of calibration curves obtained using glass certified standards and local standards. We have demonstrated that LIBS serves for the noninvasive/micro-destructive, quantitative chemical characterization of most of the analysed historical glasses. Furthermore, this work establishes a comparison between LIBS analysis of glasses in the ns and fs regimes on one hand, and on the other hand with the results obtained 2 using XRF. The procedures and protocols here proposed can be applied for in-situ study of historical glass collections, regardless of their size, provenance and chronology.

“…The size distribution of the sample aerosol is a critical parameter for the complete evaporation, atomization or ionization of the analytes; ablated particles larger than 150 nm for glass samples 6 and 400 nm for metals 7 are not completely vaporized and ionized in the ICP. The particle size distribution is a function of various parameters such as, the laser wavelength, [8][9][10][11] laser irradiance, 12,13 laser pulse length, 13,14 depth of the crater, cell geometry [15][16][17] or the type of carrier gas. 10,18 For brass and glass materials, it is recognized that the total elemental composition of all transported particles represents the bulk composition of the solid sample, whereas individual particles possess a different elemental composition (deviating from the bulk composition).…”
