“…[1][2][3][4][5][6][7][8][9][10] As no material pre-treatment is needed and due to the swiftness of analysis, this technique offers an attractive solution for a wide range of applications. [8][9][10][11] The analytical performance of LIBS depends strongly on the choice of experimental conditions that influence the laser-produced plasma characteristics.…”

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.

“…Recent sensing system has been rapidly improved in addition to upgrading software technology and much more precise analysis, combining size, shape, color, density, luster, density, chemical composition, etc., have been carried out in one sorting process. Recently, LIBS (laser induced breakdown spectroscopy) analysis has become an interesting detecting system also for sorting and will be able to be a strong method to identify the materials to be recovered near in the future [3][4][5][6][7].…”

Abstract. Physical separation is one of the key technologies in the field of resources recycling for concentrating targeted component(s) and could create an environment friendly recycling process because of their relatively low energy consumption and low cost required. Physical separation process involves two kinds of stages, one is comminution for achieving the liberation of targeted component(s) and the other is real separation of target component(s) from the others. Recently a variety of smart comminution processes, involving mechanical and electrical disintegration as well as the pre-treatment, is developed for aiming selective breakage of phase boundaries of the solid materials to be recycled. The paper indicated several examples of such processes, (1) selective mechanical comminution for effective utilization of aluminum dross, (2) two-stage comminution for recovering minor rare metals from electronic appliances, and (3) concentration of platinum group metals from spent automobile catalyst. The paper also mentioned a sensor based sorting (SBS) process by combining several sensing systems, XRT and XRF, to achieve a horizontal recycling of scrap aluminum.

“…Thus, by delaying the signal collection, the continuum background can be rejected; this is called the time delay, t d . [9] The species primarily atomized or ionized in the plasma tend to exist in their neutral or singly-ionized forms, whereas doubly-or triply-ionized species are not likely to be observed in air due to their higher ionization potentials. Neutral or singly-ionized lines are signified by (I) or (II), respectively.…”

In this physical chemistry laboratory, the students develop experience in using Laser-Induced Breakdown Spectroscopy (LIBS) to analyze spectral emission data from to determine lifetimes of neutral and singly-ionized titanium species in LIBS plasmas. LIBS is a spectroscopic technique that focuses a high power laser on a surface. The laser heats, ablates, atomizes, and ionizes the surface material which creates a plasma. The light from the plasma is then spectrally resolved and detected. For LIBS experiments, the data can be collected using gated (using time delays and gate widths) or non-gated detection; this experiment uses gated detection taken at various time delays. The time delays used ranged from 0 to 60 µs to create the time decay curves. After creating the time decay curves for the titanium species used in this experiment, the students were able to examine the curves which illustrated the behavior of the neutral and singly-ionized titanium species and also gained experience calculating lifetimes.
