“…The instrument was optimized for measurements at 120 m away from the samples and it has been employed, for instance, for the stand-off detection of explosive residues on solid surfaces. 177 Recently, Bertolini et al 178 have reported the development of the first mobile instrument for double-pulse LIBS analysis, named Modì (Mobile Double-pulse Instrument for LIBS analysis). The instrument employed a double-pulse Nd:YAG laser source capable of emitting two collinear laser pulses (1064 nm, 50 to 120 mJ pulse energy, 0 to 60 µs interpulse separation and 10 Hz double-pulse repetition rate), a focusing lens and collecting optics (lens and optical fiber cable), a sample chamber containing a motorized X-Y stage and an optical microscope for precise sample positioning and microanalysis, a computer, and an echelle spectrograph associated with a bi-dimensional ICCD.…”

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...

“…The laser can be directed anywhere, allowing the researcher to work near to the sample or far from it, for instance with dangerous samples like explosives [22] in Stand-off configurations. A Stand-Off LIBS (ST-LIBS) is defined as a LIBS set-up which allows a remote, noncontact material detection-characterization over a distance of at least several meters [23].…”

Laser-induced breakdown spectroscopy (LIBS) is a technique that provides an accurate in situ quantitative chemical analysis and, thanks to the developments in new spectral processing algorithms in the last decade, has achieved a promising performance as a quantitative chemical analyzer at the atomic level. These possibilities along with the fact that little or no sample preparation is necessary have expanded the application fields of LIBS. In this paper, we review the state of the art of this technique, its fundamentals, algorithms for quantitative analysis or sample classification, future challenges, and new application fields where LIBS can solve real problems.

“…ARL has used LIBS for the detection of Halon alternative agents (19,20), tested a field-portable LIBS system for the detection of lead in soil and paint (10), studied the spectral emission of aluminum and aluminum oxide from bulk aluminum in different bath gases (21), performed kinetic modeling of LIBS plumes (22)(23)(24)(25), and demonstrated the detection and discrimination of geological materials (18,(26)(27)(28)(29)(30)(31), plastic landmines (32,33), explosives (34)(35)(36)(37)(38)(39)(40)(41)(42), and chemical and biological warfare agent surrogates (43)(44)(45)(46)(47). ARL has also published a number of reviews on LIBS (8,(48)(49)(50)(51)(52).…”
