“…In 2002, Song et al 6 cited additional commercial instruments, such as the MΔ5095 from MelΔok and the Tracer 2100 from Advanced Power Technologies. However, an evaluation of the present configurations of these instruments was not possible because their websites are no longer accessible.…”

“…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.…”

“…In addition, the system could study a sample surface with the help of scanning electron microscopy (SEM). The precipitates formed on the surface of the aluminum alloy are (Cu,Fe,Mn)Al 6 and CuMgAl 2 and they were distinguished by means of the emission spectra obtained after scanning of the surface with a spot size on the order of a few µm. It was demonstrated, in the two papers, that both systems can differentiate the precipitates, but only in the first paper was it possible to make a quantitative analyses of the precipitates (the results were compared with those obtained by a electron microprobe X-ray analyzer), resulting in a more complete definition of the contour map of the sample surface.…”

“…The effect of the electron density on the line width, knowing as Stark effect, allows relating these parameters by the equation, 10 16 )w (6) where w total is the line half-width at half maximum (HWHM), P is a parameter giving the ion contribution, r is the ratio of the mean distance between ions to the Debye radius and w is the HWHM Stark width caused by the electron density. The values for w can be found in the literature for P = 0 and n e = 10 16 electrons cm -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...

In laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) the aerosol analyzed by ICPMS is generated by evaporating (ablating) a solid sample by means of a high-energy pulsed laser beam, which is focused on the sample surface. The ability to concentrate laser energy into an area as small as 4 μm in diameter for current equipment enables spatially resolved elemental analysis of major, minor, and trace elements and isotope ratio measurements in almost any solid material [1][2][3][4][5]. The development of this technique started in 1985 when Alan Gray presented the very first attempt at quantitative analysis of geological materials using LA-ICPMS [6]. The general setup of LA-ICPMS has not undergone fundamental changes since this initial configuration, while technical improvements of laser sources, beam delivery optics, and ICPMS instrumentation led to better performance and an increasing range of applications until today. These applications range from geochemical studies over material sciences and technology into biochemical and even medical applications. Forensic studies of many kinds are routinely carried out, and quality control of production processes is an increasing field where this technique is employed. In general, LA-ICPMS is a valuable tool in elemental trace and ultra trace analysis whenever spatially resolved determinations are required or when sample consumption shall be minimized. Even for bulk analysis, LA-ICPMS may be considered as it eliminates the need for sample digestion and minimizes the occurrence of solvent-based spectral interferences, which can be a severe limitation in ICPMS when using conventional solution nebulization.LA-ICPMS basically consists of the following components:• The laser source and beam delivery. Different pulsed lasers are currently available for LA-ICPMS, which primarily differ in wavelength, pulse duration, and pulse energy as well as in beam geometry and energy distribution. The beam delivery in most cases consists of energy adjustment, steering and shaping elements, and an objective for focusing and observation. Beam shaping is carried out toHandbook of Spectroscopy, Second Edition. Edited by Günter Gauglitz and David S. Moore.
