“…It appears as a highly promising analytical tool in a broad spectrum of applications because of its simplicity and modularity in instrumentation, speed of analysis and easy automation, features very important in industrial process control or screening applications which require handling of large numbers of samples in short times. Furthermore, portable versions of LIBS technology have been introduced recently with emphasis on field expeditions related to environmental and security applications [72,21,60]. Moreover, the LIBS technique is of extreme value in archaeological applications because it is virtually nondestructive [52].…”

“…In addition to their portable instrument, described previously, 173 Palanco et al 176 recently reported a new mobile LIBS instrument with larger dimensions, but having the capability of making measurements up to hundreds of meters away from the sample. For that, the instrument employs optical components similar to those used in telescopes in order to send the laser beam and gather the emitted radiation.…”

“…In 2003, Palanco et al 173 reported a portable LIBS instrument employing a more robust measuring probe and an automated analytical procedure for quantitative determination controlled by home-made software, allowing, for instance, to check whether the sample surface is prepared for the analysis and to detect possible interferents before the quantitative measurements. The instrument design is similar to those of previously described portable instruments, but employing a mount attached to the output of the Nd:YAG laser source (1064 nm, 50 mJ pulse energy) at the measuring probe to support the focusing lens and collecting optics (lens and optical fiber cable), enabling their ready adjustment and providing sampling stability and ease of handling.…”

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...

“…For complex samples, the calibration function of a given element depends not only on the concentration of said element but also on the concentration of the remaining sample constituents. As a result, calibration curves are best obtained using multivariate calibration on a sample set diverse enough to cover the concentration space of interest [3,4].…”

“…In fact, the growing demand for in-situ results has been accompanied by the increasing scientific efforts devoted to the research and development of field deployable analytical techniques and instruments. In this sense, atomic emission spectrometry has received a significant share of the work, the advances in spark emission spectrometry and laser-induced plasma spectrometry being the most remarkable [3,4]. Although both techniques rely on the same measurement principle, spark spectrometry is handicapped by the nature of the atom source it employs.…”

-The present work aims to assess Laser-Induced Plasma Spectrometry (LIPS) as a tool for the characterization of photovoltaic materials. Despite being a well-established technique with applications to many scientific and industrial fields, so far LIPS is little known to the photovoltaic scientific community. The technique allows the rapid characterization of layered samples without sample preparation, in open atmosphere and in real time. In this paper, we assess LIPS ability for the determination of elements that are difficult to analyze by other broadly used techniques, or for producing analytical information from very low-concentration elements. The results of the LIPS characterization of two different samples are presented: 1) a 90 nm, Al-doped ZnO layer deposited on a Si substrate by RF sputtering and 2) a Te-doped GalnP layer grown on GaAs by Metalorganic Vapor Phase Epitaxy. For both cases, the depth profile of the constituent and dopant elements is reported along with details of the experimental setup and the optimization of key parameters. It is remarkable that the longest time of analysis was ~10 s, what, in conjunction with the other characteristics mentioned, makes of LIPS an appealing technique for rapid screening or quality control whether at the lab or at the production line.Index Terms -surface analysis, laser induced plasma spectrometry, in-situ.
