“…The standard glasses are soda-lime-silica glass (Gl-1, standard glass Nº 7), lead oxide-potassium oxide-silica glass (Gl-2, standard glass Nº 8) and amber soda-limesilica glass (Gl-3, SGT 10) provided by the Society of Glass Technology, UK. The homemade model glasses (Gl-4 to Gl-7) were prepared on the occasion of a previous study 28 , and were chosen due to the similar chemical composition as the historical ones subject of the present investigation.…”

“…Although LIBS has been used in several archaeometrical studies of different cultural heritage materials, [21][22][23][24][25][26] those devoted to historical glasses are scarce. These studies have focused on finding the optimal LIBS parameters for the analysis of model soda lime silicate 27 and historical lead silicate glasses, 28 on the characterization of chromophores and opacifiers of ancient glasses, and on degradation pathologies. [29][30][31] LIBS has proved to be effective for studying glasses from a wide variety of perspectives.…”

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.

“…This approach to sample introduction has the desirable features, since a homogeneous analytical sample is easily obtained, external standards are easily prepared, and internal standardization or isotope dilution is straightforward [10]. However, various sample types exist for which dissolution is slow, difficult or inconvenient [11,12]. Direct analysis of solid samples offers several benefits compared to traditional sample preparation techniques such as acid digestion and dry ashing.…”

ABSTRACT. Laser-induced breakdown spectroscopy (LIBS) is an emerging analytical technique, which can be used to perform elemental analysis of any material, irrespective of its physical state. In this study, the LIBS technique has been applied for quantification of total Cr in soil samples collected from polluted areas of Brits, North West Province, South Africa. A Q-switched neodymium-yttrium aluminium garnet (Nd-YAG) laser (10 Hz, λ = 1064 nm) was employed for generation of a laser-induced plasma on the surface of the soil sample. The atomic emission lines were recorded using an Andor Shamrock SR-303i spectrometer, fitted with an intensified charge-coupled device (ICCD) camera. Detailed investigation of experimental parameters such as gate delay time, gate width and laser pulse energy was conducted. Soil samples were dried, finely ground, sieved and thereafter pelletized before LIBS analysis. Calibration curve for the quantification of Cr was constructed using certified reference materials of soils and sediments. The concentrations of Cr in soil samples varied from 111 to 3180 mg/kg. In order to test the validity of the LIBS results, inductively coupled plasma-mass spectrometry (ICP-MS) was also employed for determination of Cr. The results obtained using LIBS were found to be in good agreement with those of ICP-MS.

“…At this point, the characteristic atomic emission lines of the elements can be observed. It has been successfully applied before in qualitative analysis and to sort different kinds of materials like paper [1], plastics [2], glasses [3], cinematographics films [4], and so on. This technique has been used because it is powerful, has online possibilities, performs quick classification, and so on.…”

Quick online classification allows the installation of the equipment in the line of work. In this sense, the laser-induced breakdown spectroscopy (LIBS) technique offers all the possible advantages: speed, possibility of online analysis, nondestructive, and so on. For the present work, a 350 mJ laser and Mechelle spectrograph were used. Analysis of the data with principal component analysis (PCA) allows an automatic classification of the aromatic herbal products like tea and camomile in a nondestructive and fast way.
