“…The main aim of this study is the application of LIBS technique for rapid detection of toxic elements in cosmetic products like lipsticks which is a fluid (neither liquid nor solid) and not trivial to analyze by conventional methods where lengthy/or laborious sample preparation procedures and chemicals are required. It is worth mentioning that in the past LIBS technique for detection of these toxic elements in paint, soil, rock, iron slag, oil residue, oil spills and volcanic eruption samples [9][10][11][12][13][14][15][16][17][18][19]. However most of these samples were in solid phase and LIBS could be easily applied for analysis of such samples.…”

“…Los trabajos previos sobre el uso de LIBS en el análisis de H y de C en muestras de origen orgánico son escasos (Cremers and Radziemski 2006) (Radziemski 2002) (Pasquini et al 2007) (Fantoni et al 2008). Esto se debe al ensanchamiento de las líneas debida a la recombinación del H y el C en el propio plasma, así como a la disminución en la intensidad de dichas líneas cuando el plasma es producido a presión atmosférica (Aguilera et al 2009) (Aragón and Aguilera 2008).…”

Análisis de plasmas inducidos por láser con excitación multipulso para el proceso de ablación de areolas de TunaLaser-induced breakdown spectroscopy analysis with multi-pulse excitation for ablation process of tuna areolas seguimiento en tiempo real de un proceso de ablación láser, incluso para muestras de composición compleja. Para el monitoreo de un proceso industrial, esta herramienta sería más adecuada, si se cuenta con una calibración del equipo y un protocolo particular definido. En el trabajo, se ejemplifica esta posibilidad para el caso de la ablación láser de areolas de Tuna (fruto de el Opuntia ficus-indica).Método: Se realiza el análisis LIBS de muestras de tuna, tanto en las areolas como en la corteza.Para la excitación del plasma se emplea un láser de Nd:YAG en régimen de Q:Switch con tren de pulsos. Con el objeto de asegurar el reconocimiento de las líneas en los espectros LIBS, se realizaron análisis en patrones de composición conocida, estableciéndose un protocolo para la interpretación de los espectros.Resultados: Se logró una clara lectura de la línea de H ubicada en 656.2 nm. Se estableció un protocolo para la interpretación de los espectros, que permitió la identificación de 49 picos característicos. Finalmente, se determina la composición para la corteza y la areola y se lleva a cabo una comparación cualitativa entre éstas.Discusión: Se muestra que la excitación láser en forma de tren de pulsos, entendido este régimen como modalidad particular del Q:Switch, permite la determinación eficiente de elementos, con una adecuada relación señal-ruido. Por otra parte, que es posible determinar diferencias composicionales evidentes entre corteza y la areola, lo cual permite monitorear un proceso de ablación de areolas con láser de manera simple.Palabras claves: Opuntia, plasma, láser, LIBS. Recepción: 16-02-10Aceptación: 04-03-10 Method:The LIBS analysis of tuna samples takes place, both in the areola and in the cortex. For the plasma excitation we uses a Nd: YAG laser with special Q:Switch scheme: The pulse train emission regime. In order to guarantee the lines recognition in the LIBS spectra, before experiments widh samples, we takes the spectrum of well known composition standarts, establishing a protocol for the interpretation of spectra.Results: A clear reading for the H line located at 656.2 nm was obtained. A simple protocol was established for the spectra interpretation, which allowed the identification of 49 characteristic peaks. Finally, the composition to the cortex and the areola were determined and carried out a qualitative comparison between them. Discussion or Conclusion:The results shows that the laser excitation in pulse train form, understood as a particular form of Q: Switch regime, provides an intense plasma emission and efficient elements determination, with adequate signal to noise ratio. Moreover, it is possible to identify compositional differences between crust and areola, which can permits to track the laser ablation of areolas process in a simple way.

“…A second -less common -application is laser ablation mass spectrometry (LAMS) [27,28], where the ions formed during the ablation process are directly transferred into a mass spectrometer for analysis. Both former approaches are somewhat limited for quantitative analysis of samples, where matrix-matched calibration standards are not readily available [29][30][31]. Matrix-assisted laser desorption and ionization (MALDI) [32] may be considered an approach similar to LAMS.…”

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.
