“…36 In particular, the flat-top beam profile of the 193 nm ArF excimer laser used in this work is ideal for this kind of application, as documented in previous works. [37][38][39] In principle, by using an output energy significantly exceeding the threshold and a sufficiently wide laser beam diameter, it is possible to obtain representative compositional data throughout the process of ablation, as long as a value of 6 for the depth/ diameter ratio is not exceeded, 34 although for this particular laser system it has been recommended not to exceed a depth/diameter ratio of 1.5, in order to achieve uniform flat-bottomed craters.…”

In this work, several red-colored paintings of post-Paleolithic schematic style found in 10 different shelters in the vicinity of the Vero River (Huesca) were sampled and subjected to analysis by means of scanning electron microscopy-energy-dispersive X-ray spectrometry (SEM-EDX), Raman spectroscopy, and laser ablation-inductively coupled plasma mass spectrometry (LA-ICPMS). The goal of this research was to obtain meaningful information on the samples composition, in order to establish differences or similarities among them. The combined use of these techniques proved beneficial, as Raman data permitted structural information on the compounds present (hematite was identified as the main pigment, whereas calcite and gypsum are the main components of the substrate layer, as well as of the accretions that covered the pigments) to be obtained, while the quantitative values obtained by SEM were suitable for the use of Ca as internal reference during LA-ICPMS analysis. However, it was this latter technique that provided the most relevant data for fingerprinting purposes. The potential of this technique for obtaining spatially resolved information allowed the multielement quantitative analysis of the pigment layer, in spite of the presence of superficial accretions. The sensitivity of the technique permitted the determination of more than 40 elements present in a wide concentration range (from microgram per gram to 10% level) with minimum sample consumption (approximately 900 ng for each sample, corresponding to five replicates). Finally, in order to establish significant differences, only those elements showing a high correlation with Fe (As, Co, Mo, Sb, Tl, and Zr, in this case) were selected, as it is expected that these were truly present in the original pigment, while others could have migrated into the pigment layer throughout time. By using this information, it seems feasible to discriminate between various paint pots, as demonstrated for the samples under investigation.At the end of the Ice Age, the great herds that had provided sustenance for the Paleolithic hunters disappeared from France and Spain. In the large forest areas that flourished owing to the warmer climate, groups of deer and related species lived. These animals were fast and elusive and, thus, much harder to hunt. As a consequence, man had to modify his hunting techniques, as well as forage for the seeds and fruits that the forest provided or the fish that were available in rivers or on the coast. Cooperation was essential, and this change was reflected in the art of this postPaleolithic period. 1 Bands of such hunter-gatherers left a record of their activities in shelters scattered throughout the Iberian Peninsula, among other regions. The differences with Paleolithic paintings are evident, as a simpler silhouette technique emerges. Moreover, the new paintings seem to have a clear narrative meaning, featuring a higher proportion of hominine figures. 2 Investigation of these paintings can provide relevant hints about the technological level as ...

“…lA-icP-MS is a technique determining the ion release in the solid materials reliably and in a short time (31). lA-icP-MS also gives the opportunity for multi-element analysis of solid materials and is being used effectively in many fields (4,10). With LA-ICP-MS, along with food, marine speciation, solids and sediments, archaeological findings, botanical tissues, and environmental materials, it is now possible to directly examine biological samples such as teeth, hair and nails as well.…”

Apresentam-se sistemas de análises em fluxo propostos para a quantificação de elementos e espécies por diluição isotópica (ID) utilizando espectrometria de massas com fonte de plasma acoplada indutivamente (ICP-MS). Detalham-se os esquemas para adicionar em linha a solução isotopicamente enriquecida à amostra. São relatadas as aplicações em meio aquoso e outras com transferência do analito para a fase vapor, seja por processo de vaporização eletrotérmica, geração de vapor ou ablação por laser. Apresentam-se as aplicações com quantificação de espécies por ID caracterizadas pela adição do isótopo enriquecido, antes ou após a separação das espécies, seja por cromatografia a líquido, a gás ou por eletroforese capilar acoplada a ICP-MS. As principais equações envolvidas na quantificação por ID e as principais fontes de erro são descritas. São discutidas as mudanças introduzidas na estratégia de quantificação temporal por ID de elementos e espécies pela calibração do fluxo de massas da amostra e do isótopo enriquecido adicionado.Flow analysis has been utilized for elemental and species quantification by online isotope dilution inductively coupled plasma mass spectrometry (ICP-MS). Online isotope dilution (ID) herein refers to strategies promoting the addition of enriched isotopic solutions to the samples while flowing towards the plasma. Applications of online ID's are commonly performed in aqueous media, however, in some processes the analyte transference to the vapor phase using electrothermal vaporization, vapor generation or laser ablation is also required. Flow diagrams to perform online pre or post-column spiking with the enriched isotope for quantification by ID in speciation analysis by liquid chromatography, gas chromatography or capillary electrophoresis devices coupled to ICP-MS are presented. The main figures of merit and equations applied to elemental and species quantification by ID in flowing schemes are assessed.
